Separation between galaxy- and starlike sources. The figure shows the SEXTRACTOR parameters CLASS_STAR plotted vs. ﹩{\mu }_{V,0,\max }﹩ for detected model galaxies (colored dots) and nonartificial sources (gray dots). Low CLASS_STAR values indicate extended galaxy-like sources, and high values denote compact starlike sources. Here μV,0,max denotes the maximal surface brightness measured by SExtractor, and ﹩\langle {\mu }_{V,0}{\rangle }_{50}﹩ corresponds to the intrinsic surface brightness of the models, according to which they are color-coded. The top panel shows the resulting detection from the SEXTRACTOR run with DT1 = 1.3σ, and the bottom panel shows additional detections from the SEXTRACTOR DT2 = 0.8σ run, which were not detected with the DT1 setting. The dashed lines indicate the CLASS_STAR parameter cuts below which we considered the detected sources for our catalog. The cuts correspond to CLASS_STAR ≤0.3 for sources with μV,0,max ≥ 20 mag arcsec−2 and CLASS_STAR ≤ 0.8 for sources with μV,0,max < 20 mag arcsec−2.
