The Center for Astrophysics REDSHIFT CATALOGUE John P. Huchra, Margaret J. Geller, Cathleen M. Clemens, Susan P. Tokarz and April Michel Harvard-Smithsonian Center for Astrophysics 60 Garden Street Cambridge, MA 02138 6 February 1995 I. Introduction The CFA REDSHIFT CATALOGUE incorporates much of the latest velocity data from the Whipple Observatory and other sources as well as velocities from earlier compilations such as the Second Reference Catalogue of de Vaucouleurs, de Vaucouleurs and Corwin, the Index of Galaxy Spectra of Gisler and Friel, and the Catalogue of Radial Velocities of Galaxies of Palumbo, Tanzella-Nitti and Vettolani. It includes BT magnitudes, some UGC numbers and increased "accuracy" in the velocity source information. The format for the catalogue is: (A11,I2,I2,F4.1,A1,I2,I2,I2,F5.2,I5,I3,A1,..........) A more detailed description of the format can be found in Table 1. By definition, we are continually adding information and updates of the catalogue will be made available at reasonable intervals. The data presented here have primarily been assembled for the purpose of studying the large scale structure of the universe, and, as such, are nearly complete in redshift information, but are not necessarily complete in such categories as diameter, magnitude and cross-references to other catalogues. Additional information of that type will be added in later editions. Much of the data in the northern hemisphere owe their origin to Zwicky's catalogues of galaxies (Zwicky et al. 1961-66; Zwicky 1971; Zwicky, Sargent and Kowal 1975). The authors of this catalogue would like to express both their gratitute and reverence for Zwicky's monumental efforts. II. Velocities Please note that the velocities quoted are heliocentric and that redshifts (z's) have been converted to velocity via v = z times c, where c = 299,792.5 km/s. Redshift is defined as z = (lambda - lambda(o)) / lambda(o). We quote heliocentric velocities to allow individual users to correct to their own favorite galactocentric or "local groupocentric" or "Virgocentric" or even the micro-wave background frame. We have endeavored to properly remove such corrections before entering data into the catalogue, but confusion still remains in those cases where the authors do not explicitly state what corrections were made. In those cases we assume 300*sin(l)*cos(b) km/s to be the galactocentric correction. Note also that now that velocities of precisions less than 30 km/sec are commonplace, the correction to heliocentic is mandatory! We strongly urge all other authors to follow this convention. Basic radial velocity sources are listed in Table 2. Velocities with negative source designations are still in the private domain and cannot be used without the appropriate owner's consent. The additional source information in columns 43 and 44 is the number of the paper under the broader source categorization. Initially this was alphabetic, but as more recent papers are added, the numbering scheme has become chronological. Again, beware of blanks, which may signify source zero, but most likely indicates that this information has not yet been updated. In any case, the zero/blank paper for each source is likely to represent the largest number of velocities available from that source (e.g. the Second Reference Catalogue). The RFN column in the catalogue contains the file number of the spectrum which we have obtained for that galaxy. If this column is blank, we have not measured the galaxy. We have tried to fill this column in for all entries in zcat, not just with velocity entries measured by us. Objects listed in the catalogue that have no velocity and no listed velocity source (in the northern hemisphere) will be observed as part of the CfA survey extension. Give us time! (in particular, telescope time....). In some cases, faint members of studied clusters are included to help users of this catalogue determine which galaxies have been measured and which remain. IIb. Velocity Errors In general, the errors listed for velocities are the errors quoted by the original source. (i.e., random errors are quoted and systematic ones are neglected.) The only exceptions are where multiple measurements have significantly improved the velocity precision. Many sources quote errors that are really the internal mean error - e.g. the variance in the velocities measured from multiple lines in a single spectrum of a galaxy. These often do not include errors in zero points, errors caused by mis-centering the galaxy in the slit, other instrumental offsets, etc., and are always underestimates of the true external error in the velocity estimate. Some sources are better than others; velocity errors from the CfA survey and most 21-cm sources are nearly within unity of the true external error (CfA errors are only about 10-20% low), while the uncertainties quoted in some older works, such as the RC2 and the RSA, are underestimates by more than a factor of two (see, for example, Sandage 1978). For several more detailed analyses of velocity uncertainties, see Lewis (1983), Rood (1982), Tifft (1990) and references therein. A small number of our velocities are listed with the notation "poor velocity." These are weak cross-correlation velocities or velocities from single emission lines that need to be checked. We will do that. In general, there is enough information in the spectra to suggest that they are nearly correct (but I wouldn't stake my first born child on them). III. Magnitudes Magnitudes for galaxies are a persistent and pesky problem. We have tried to do our best to adopt a more or less uniform system for the largest number of galaxies. That system is the B(0)-Zwicky system (Huchra 1976). Magnitude sources for quoted values are given in Table 3. B(T) magnitudes, when available, are given in columns 59-63. These are generally about 0.4 magnitude brighter than magnitudes on the B(0)-Zw system. Some additional galaxy magnitudes, especially for objects in deeper surveys, come from digital scans of photographic plates - mostly in the photographic J and R bands. These magnitudes, by definition, are rarely easily converted into the more standard isophotal or total photographic B systems; each observer requires different zero point and color corrections. Some magnitudes have also been entered from the StScI Guide star scans (G) and from other such sources. Until proven otherwise and properly calibrated, these magnitudes are not to be trusted}. Temporarily, we have derived very approximate corrections from other systems to the B(0)-Zwicky system. These are given for sources 3-7 as: Magnitude Source - 3 B(0) = M + 1.38 Magnitude Source - 4 B(0) = M + 0.34 Magnitude Source - 5 B(0) = M + 0.5 Magnitude Source - 6 B(0) = M + 0.4 Magnitude Source - 7 B(0) = M + 0.5 Magnitude Source - A B(0) = M + 0.4 Magnitude Source - R,r B(0) = M + 1.6 for T < 1 Magnitude Source - R,r B(0) = M + 1.2 for 0 < T < 6 Magnitude Source - R,r B(0) = M + 0.9 for 5 < T Magnitude Source - V,v B(0) = M + 1.0 for T >1 Magnitude Source - V,v B(0) = M + 0.7 for T >1 Magnitude Source - J B(0) = M + 0.4 (approximately). Note that these corrections are NOT in ZCAT, but rather represent suggested corrections for future and further use. "T" is the deVaucouleurs' T-type described below. Magnitudes are taken preferentially from the 1st Reference Catalogue of de Vaucouleurs - B(0) (magnitude source 0), Harvard Corrected (magnitude source 2), and then from the Zwicky Catalogue (magnitude source 1). Magnitudes from other sources are used only when necessary and/or available. As mentioned above, this choice of system maximizes the number of galaxy magnitudes available and will allow for easy conversion to other systems given diameter and morphological type information (e.g. the BT system). Note that we have begun to include corrected Blue magnitudes from the RC3, as magnitude source "A"; these should be nearly identical to BT magnitudes (source 6), but again may not be of high quality unless based on actual photoelectric or CCD photometry. Magnitudes for many faint sources have been derived from either CCD or photoelectic photometry (particularly for AGN, Hewett and Burbidge 1993). IV. Morphological Types Morphological types are de Vaucouleurs' T types from the RC2, Uppsala Catalogue and the Revised Shapley-Ames Catalog. Some additional types have been defined for peculiar and un-typed objects and for objects that are in catalogues of extragalactic objects but are really galactic in nature: 33 = Reflection Nebula, misclassified elsewhere as a galaxy. 32 = HII Region, misclassified elsewhere as a galaxy. 31 = HII Region, part of another galaxy. 30 = Planetary Nebula, misclassified elsewhere as a galaxy. 28 = Globular Cluster, Extragalactic 27 = Globular Cluster, Galactic 26 = Open Star Cluster 25 = Plate Flaw, Star, etc. misclassified elsewhere as a galaxy. -------------------------------------------------------------------------------- 20 = Sprial galaxy (generic) 16 = Irr II 15 = Peculiar or untyped galaxy 11 = Compact Magellanic Irr (Extragalactic HII Region) -6 = Compact Elliptical (same designation as DV) -7 = Elliptical (generic) -9 = QSO/AGN, stellar, usually at high redshift We have decided to retain information on galactic objects misclassified as galaxies, on HII regions that are parts of other galaxies, and other such objects to prevent their inclusion in future lists of galaxies. Users should remove objects of type greater than 20 before using this catalogue as a simple galaxy catalogue --- otherwise you'll get all the HII regions in M101 listed separately as well a few plate flaws, stars and other assorted junk! We have also started (Fall of 1991) to include moderate redshift objects (z 1.95 Jy. ZCAT also contains all the data from the Nearby Galaxy Catalogue of Tully and Fisher (1987), and is being continually updated with the data for the UGC catalogue survey of Bothun et al. (1986). ZCAT also contains all of the published data for the galaxies in the CfA Redshift survey extension to m(Zw)=15.5. At present, these are the data for the first CfA slice: B leq 15.5 and 26.5 deg leq delta leq 32.5 deg 8h leq alpha leq 17h (Huchra et al. 1990). In addition, ZCAT contains (but without complete velocity information) all the Zwicky catalogue galaxies with m(B) leq 15.5 in the CfA survey extension. VII. Nomenclature, Comments, and Identifications In this catalogue, we rely as much as possible on good positions for proper identifcation of the galaxies listed. In clusters we also rely on published finding charts. In many cases, several authors have published velocities for the same galaxy with different ID's and discrepant positions. We are trying to "standardize" cluster id's by using Dressler's (1980) numbers in the comment field. We have done our best to remove such degeneracies, but know that some such duplicates still exist in the catalogue. For good examples, one can look at the recent "deconfusing" of part of the NGC and Zwicky catalogues by Thomson (1991, 1992). Other errors exist in catalogues and several other groups, e.g., Paturel et al. (1991) and the RC3 group (de Vaucouleurs et al. 1991) are working hard on correcting and documenting these. Harold Corwin has also produced a revised version of the NGC/IC catalogue without many of the errors which have propagated through the RNGC (Sulentic and Tifft 1973) and NGC2000.0 (Sinnott 1988). We are incorporating these changes and corrections as rapidly as possible. We have adopted the following priorities for nomenclature. (1) If a galaxy has an NGC or IC designation (Dreyer 1898, 1905), then that is its primary ZCAT name in A11 format with the first character "N" or "I." (2) If a galaxy is in the Zwicky et al. catalogue and not in the NGC or IC, then its designation is "hhmmt+/-ddmm" where hh = hours, mm = minutes, t = tenths of minutes of time, and dd = degrees. These coordinate names are taken directly from the Zwicky et al. catalogue; they are the coordinates minus the decimal point. Better coordinates from other sources may exist and may be found in the coordinate columns. Occasionally these improved coordinates contradict Zwicky's. The Zwicky name is a 10 character designation starting in the first character. (3) All other anonymous galaxies have names of the form "hhmm+/-ddmm" or "Ahhmm+/-ddmm." Multiple components or multiple galaxies at nearly the same coordinates are designated by trailing letters such as "hhmm+/-ddmmB" where the "B" indicates the second object at that location. These addtional letter designations are usually added in order of right ascension. Many galaxies are listed in more than one catalogue --- it is not unusual for a galaxy to be in Zwicky, Nilson, the MCG, Markarian's lists, etc. We have tried to include complete identifications from the UGC, ESO and Markarian lists, but other identifcations are given for only a small fraction of the galaxies in the catalogue. (Usually they have been entered when the measurers provide machine readable catalogues of their data with all the other names listed). When they exist, MCG designations will be found in the comment field and will generally look like "Mnn-mm-ppp," where nn is the declination zone (negative zones are preceeded by "-"), mm is the sky survey field in the zone running from 0 hours, and ppp is the galaxy number. ESO designations like "ESOnnn-(I)Gmmm," where nnn is the ESO field number and mmm is the galaxy number on the plate, appear as nnnmmm in the same column as the UGC galaxies. We have not preserved the distinction between isolated (-G) and interacting (-IG) galaxies in ESO. Even though all coordinates in this catalogue are quoted to 0.1s and 1", the actual precision of positions for galaxies varies considerably. In general, coordinates from the Zwicky or Nilson catalogues are quoted to 1' and are precise to a little better than that. Coordinates from the MCG are often off by more than 2'. Galaxies from the above catalogues have coordinates quoted to only the nearest 1' and 6s. Coordinates precise to 5"-6" have been taken from the RC2, from Spellman, Madore and Helou (1989), Dressler (1980), the ESO and Guide Star catalogues and similar lists. In some small number of cases, usually in the inner regions of clusters of galaxies, coordinates to this precision have been measured by us or our collaborators. A growing subset of galaxies in this catalogue have coordinates measured to arc-second precision via measuring engines or plate scanners. This is particularly true for Seyfert galaxies, Markarian galaxies, radio sources and other AGN, and also for data sets that come from multiple-fiber observations or new, deep, small area surveys. Coordinates for IRAS sources extracted from the PSC are accurate to 20"-30", while strong sources that have been add-scanned will have more precise coordinates. VIII. Other Notes In a very few instances we have listed discrepant velocities (where two velocity measures disagree by more than double their combined external errors) found by other sources in the comment field - e.g. 1234(9) indicates a velocity of 1234 from source 9. Effort is being made to clear these up by remeasuring the galaxies. In general, the velocities listed are the best available in terms of the quoted measurement errors and the reliablity of the source (some people persist in quoting errors considerably smaller than their true external errors). In only a few cases have we attempted to average high quality data to produce slightly better values. For almost all objects only one velocity is available. We do not think it appropriate to average low quality data with the newer, significantly better velocities available from 21-cm work and relatively high dispersion optical work. We do not average measurements made by different instruments. The purpose of this catalogue is to be a complete list of galaxies with radial velocities for mapping and statistical studies. (Observers who feel that their velocities have been slighted for poorer velocities should contact J.P.H.) In several cases, we have omitted velocities derived from detailed HI maps of galaxies - primarily because a single dish measurement of sufficient quality is usually extant. The best quality optical and HI observations have velocity errors < 10 km/sec, which are well below the internal velocity dispersions of the galaxies. By definition, there is some question as to what such high "precision" velocities really mean relative to the centers of "mass" of galaxies. Radial velocities greater than 100,000 km/sec will be found in the companion catalogue ZBIG.DAT. We have not been as assiduous in our efforts to maintain that catalogue (interested parties should contact Hy Spinrad for more information.) Averaged radial velocities for Abell clusters will also be found in another catalogue ABELL.DAT. The cataloguers make no claim that this issue is complete or free from errors. All galaxies brighter than B(0)=13.2 have been included, even when no velocity is available, but otherwise there is no homogeneous magnitude limit to the catalogue. Some galaxies are listed despite their lack of velocity. These are objects in complete samples that we are currently trying to observe, DDO dwarves without velocities, "DOUBLE" galaxies that have been split up for the production of North Zwicky Forty or galaxies from other interesting catalogues (e.g. Binggeli et al.'s work on the Virgo Cluster dwarves - Ref 0109). Magnitudes on systems 0, 1 and 2 are more or less equivalent but other systems have not been well calibrated and are meant only to serve as a guide to the galaxy's brightness. Some of this data is unpublished, so authors are warned against making reference until this list is formally published. We are constantly updating this list as new velocities, particularly better velocities, become available. We do not guarantee that what you see one day will be there the next! Present plans are to publish with Springer-Verlag the version we have (cleaned of zero velocity objects, etc.) this year. A fairly large number of FORTRAN based utility programs now exists for sorting and searching in ZCAT including routines to do circle searches around annuli, cuts in galactic or equatorial coordinates, etc. See John Huchra or email to Cathy Clemens (clemens@cfa.harvard.edu) for a more detailed description of these. If errors are found, as some are sure to be in a compilation this large, please report them to the author (J.P.H.). If you wish to make additions, these will be gratefully accepted --- even more so if listings include accurate 1950 coordinates and heliocentric velocities and are transmitted electronically. In this day and age, there is no need to present data in unusable formats, so we humbly request that all authors henceforth quote heliocentric velocities (or redshifts = (delta-lambda)/lambda) and reasonably accurate 1950 coordinates in publications of data and that all editors not accept papers presenting velocities in unusable forms. An HP-25 program to calculate the correction from geocentric to heliocentric velocity to a precision of +/- 1 km/sec is available from JPH. Presentation of velocities in undefined or poorly defined inertial reference frames (e.g. Local Groupocentric or the micro-wave background frame) should be avoided at all costs. Editors please take note! Special thanks are in order for all the people who have worked on this catalogue over the years - Dinah Danby, Bob Davis, Marc Davis, Ed Horine, Dave Latham, Jon Morse, Jim Peters, Suzanne Rapp, Michael Strauss and John Tonry. Several other fearless cataloguers of galaxies and galaxy properties, most notably Harold Corwin and Dave Burstein, deserve thanks if only for being the last of a dying breed, as well as for comments, corrections, classifications and data. Thanks are also extended to those other observers who have sent in redshifts (particularly those who send heliocentric z's and good, 1950 coordinates!) and corrections like Tony Fairall, Ed Groth, Riccardo Giovanelli, Martha Haynes, George Helou, Lyle Hoffman, Nathan Krumm, Otto Richter, Ed Salpeter and Wayne Warren. Lastly, we would like to thank all those people who have been willing to send us electronic copies of extended catalogues; these have certainly made our jobs significantly easier as well as reducing the probability of error on entry. This work has been supported by the Smithsonian Institution and by NASA grant NAGW-201. Some computer support has also been provided by the Digital Equipment Corporation. Thank you.
