Caption: Figure 15.

Sources detected by each method. On the diagonal, we show the median image (in a deep coadd) of all the detections produced by each method. As seen in previous figures, these are largely similar between the methods since a majority of the detections are in common. On the off-diagonal, we show detections from one method and not another method, again the median in a deep coadd. In general, the images above the diagonal look more like real sources in a deep coadd, meaning that the SED-matched methods are generally producing detections at real source locations.
