Galaxy counts per dm, plotted ∝dI_ν/dm, at the four sets of Euclid-related wavelengths. Black lines show the JWST counts at 0.88, 1.02, 1.25, and 1.63 μm. HRK reconstructions are displayed with red colors, going to the 0.8 μm at the VIS-related end. The spreads in the reconstructions between the LFE (low-faint-end) and HFE (high-faint-end) limits of the extrapolation allowed for the Schechter-type luminosity function (Helgason et al. 2012) are shown with pink shades. Dashed vertical lines mark the range of magnitudes identified for this study in Eq. (10). The JWST counts are filter-transformed to either ground-based VISTA filters or Spitzer filters at the long wavelengths (S. Tompkins, R. Windhorst, private communication). HRK reconstructions are shown at the wavelengths of 0.8, 1.05, 1.25, and 1.63 μm.
