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: 3

    Magnitudes are Vega in the instrument natural system (SOFI)

    Model data averaged over 10 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

    Solid Triangles, dotted line     : Vandame et al. (2001)  preprint

    Open Triangles , short dash      : Martini, P. 2000 astro-ph/0008328

    Crosses        , long dashed     : Metcalfe et al. MNRAS in prep.

    blue dashed line:

    5 S/N MAG_AUTO magnitude limit=19.79

    red line:

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

    a =  0.40; b = -3.37.

    Magnitude System: Vega

    Magnitude Type:   MAG_AUTO
