Sample of LBGs at z ≃ 7 from this work plotted in photometric redshift (z_phot) and absolute rest-frame UV magnitude (M_UV) space. Top: U-only sample (blue). Bottom: U + E sample (red). The red squares with a black outline indicate galaxies not recovered in the U-only sample and thus unique to the U + E sample. In both panels, we also show the candidates from V23 in the XMM-LSS and ECDF-S fields, and the HST-selected candidates from B21. The dashed grey lines show the 30%, 40%, and 50% completeness limits, as derived from the injection-recovery simulation (see Sect. 5.1). We also show the marginalised distributions in z_phot and M_UV as normalised histograms, and also overplot the distribution of the other sample as the thinner, fainter line for comparison. The mean uncertainties are shown on the bottom left.
