Differential source counts in u′, g′, r′, i′, z′, J, H, Ks (from top to bottom). Histograms show CFHTLS observations: star+galaxy counts built from u′, g′, r′, i′, z′ source catalogs from MegaPrime D1+D2 (Hudelot et al. 2012), and J, H, Ks galaxy counts taken from WIRCam D1+D2+D3+D4 (Bielby et al. 2012). Our fiducial model is shown as empty circles (without stars for near-IR bands, like the observations). For clarity, the counts in each band are regularly offset vertically downward by 1 dex from u′ to Ks. This graph shows that the magnitudes of the galaxies in the forward model agree well with the observations down to their completeness limits in all eight photometric bands.
