Comparison of the input and measured magnitudes of the detected stars (photometric error) in the J (left column) and Ks (right column) bands for some of the analyzed cases. The detection threshold is set to 3σrec. From the top: 1 × 1 (reference case), 3 × 3, 5 × 5, 9 × 9, and 15 × 15 sub-domains. The blue and red vertical stripes highlight two different bins of magnitudes with amplitude 1 mag (blue stripes) and 0.5 mag (red stripes). The photometric errors relative to the points falling in these stripes are reported in Table 4.
