Comparison of our new forced photometry and the IRAC-selected input catalog for the [3.6] (top) and [4.5] (bottom) SERVS bands. We use the original SERVS single-band aperture-corrected catalog photometry measured within an aperture of radius 1.″9 and converted to AB magnitudes. The gray-shaded region highlights the parameter space below the average 5σ detection threshold of the SERVS data. The x- and y-axis data ranges match those from the VIDEO-selected catalog comparison plots shown in Figure 5.
