Caption: Figure 2.

Distribution of known strong lenses (purple) and lens candidates (orange) used in this work. The background shading indicates the z-band observation depth, traced by the number of observations. The sample is primarily concentrated in the southern DECam footprint, consistent with the higher z-band coverage in that region.
