Fig. 8


The photometric completeness as determined from the artificial-star tests in the previous figure. The ratio f represents the fraction of input stars actually found and measured in both colors, and is plotted here as a function of magnitude in each filter. The curves drawn through the brighter parts of each set of points is a standard interpolation function of the form where m0 is the 50% completeness level and α governs the steepness of the falloff.
