Comparison of the HUDF photometry of several sources for our ABYSS reduction and the previous releases. Each panel shows the magnitude differences with their corresponding reference catalogue as a function of the object magnitude. Left panel: ABYSS vs. HUDF12. Right panel: ABYSS vs. XDF. The magnitudes are measured using fixed non-parametric apertures in each object and filter calculated with Gnuastro using the HUDF12 segmentation maps.
