Histograms of base collected, non-imputed, non-radio bands for HETDEX (clean, background histograms) and S82 (empty, brown histograms). Each panel shows the distribution of measured magnitudes of detected sources divided by the total area of the field. Dashed, vertical lines represent the 5-σ magnitude limit for each band. The number in the upper right corner of each panel shows the number of measured magnitudes included in their corresponding histogram.
