(a): Dense Basis stellar fits based on the LRD1 (left) and LRD2 (right) PSF photometry (red open circles). Data points excluded from the fits are shown using thinner lines. Solid orange, blue, and fuchsia lines depict the fits for the low- (thicker line, corresponding to the photo-z of the galaxy group), mid-, and high-z intervals. The corresponding model photometric points are shown with filled circles. (b): Dense Basis stellar fits for the satellite galaxies based on PSF (SAT0) and aperture (SAT1, SAT2) photometry, following the same color code as above. We include the HST and NIRCam transmission curves, as well as the residuals of the fits.
