Number Counts

Star Counts with comparison with Galactic model

    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: 7

    Magnitudes are Vega in the instrument natural system (SOFI)

    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 Blue Squares: EIS data

    blue dashed line:

    5 S/N MAG_AUTO magnitude limit=21.73

    red line:

    Least Squares Method: fitted log(Counts)=a*Magnitude+b

    a =  0.30; b = -1.88.

    Magnitude System: Vega

    Magnitude Type:   MAG_AUTO
