Two-dimensional histograms of various kinds of “objects” representing their distribution over the full SDC1 field for the YOLO-CIANNA model. The training area is masked when necessary. All densities are binned using the same 200x200 grid. The match and false detections are based on the scorer, while the missed ones are based on our selection function. The central coordinates of the field are RA = 0 deg, Dec = −30 deg.
