STAR COUNTS COMPARED WITH GALACTIC MODEL
              
Solid dots: EIS data
Cyan line: Galactic model, not corrected for catalog completeness 
Blue line: Galactic model, corrected for catalog completeness
Red dotted line: magnitude limit for the star/galaxy classification
Magenta dotted line: 2 arcsec - 5 sigma limiting magnitude
Number of stars in the catalog: 884
Magnitudes are Vega in the instrument natural system (WFI)
Model data averaged over 2 simulations.
Errors on model calculated as the standard deviation of the values in the different simulations.
Errors on the real counts are: 1+sqrt(N + 0.75)
Galaxy Counts
Solid Squares: EIS data
