SExtractor MAG_BEST and peak surface brightness for all non-saturated objects detected in the long exposure of the Subaru NGC 6482 field of view, including simulated dwarf galaxies with apparent sizes corresponding to the distance of NGC 6482. The SExtractor object detection parameters are given in Table 3. Black dots: all detected objects. Red dots: discovered simulated dwarf galaxies. Green dashed line: separation line adopted between galaxies and unresolved objects at the faint end (μpeak = 30 + 0.7MR).
