| 0x01 | (Sextractor) The object has neighbors, bright and close enough to significantly bias the photometry, or bad pixels (more than 10% of the integrated area affected). |
| 0x02 | (Sextractor) The object was originally blended with another one. |
| 0x04 | (Sextractor) At least one pixel of the object is saturated (or very close to). |
| 0x08 | (Sextractor) The object is truncated (too close to an image boundary). |
| 0x10 | (Sextractor) Object's aperture data are incomplete or corrupted. |
| 0x20 | (Sextractor) Object's isophotal data are incomplete or corrupted. |
| 0x40 | (Sextractor) A memory overflow occurred during deblending. |
| 0x80 | (Sextractor) A memory overflow occurred during extraction. |
| 0x100 | |
| 0x200 | (COMBO-17) potential problem from bright neighbours or reflexes from the optics (check images) |
| 0x400 | (COMBO-17) uncorrected hot pixels |
| 0x800 | (COMBO-17) erroneous photometry (set interactively) |
