Extracted Source Counts and Statistics

Figure 1 - Combined calibration field differential source counts vs. magnitude for J (top), H (center), and K_s (bottom) bands. 2MASS All-Sky PSC source counts in the same approximate area are shown in the shaded region. Figure 2 - Combined calibration field extracted source photometric uncertainties plotted versus magnitude for J (top), H (center), and K_s (bottom) bands. Figure 3 - Log 1-sigma noise (mJy) histograms for J (top), H (center), and K_s (bottom) bands for combined calibration sources.
