The left panel shows possible injection locations for SN 2025brs with the default DETECT settings. Note that in this case, the injection locations naturally fall on an elliptical isophotal contour; however, DETECT is written to identify appropriate injection locations for arbitrarily complex galaxy morphologies. Since the host galaxy is large and nearby, DETECT was able to find locations that are sufficiently spread out so they can all be injected together (i.e., they are in the same injection iteration). The injection locations in the right panel were selected with more strict criteria, and are therefore more spread out and divided over two different injection iterations, indicated by their color. The red cross in both panels indicates the location of SN 2025brs.
