Example of a photometry validation plot, comparing the catalogues for the ABELL2744 field from this work and from Weaver et al. (2024). Relative errors, Δc, are given, namely, the colours measured in this work minus those in the reference catalogues), versus the second band magnitude in this work catalogue (e.g. F444W for the F356-F444W colour). The number of cross-matched sources after excluding those with S/N <5 in any of the two catalogues or flag ≥200 in this work is also given; the blue line is the median of the distribution. Similar plots for all fields are available in the appendix.
