Completeness of extended and point-like miniJPAS sources as a function of total magnitude in the miniJPAS r band for the four miniJPAS pointings. The solid lines are the completeness curves of extended and point-like sources (red and green, respectively) obtained from the injection and detection of synthetic sources. The red (green) circles illustrate the corrected fraction of common extended (point-like) sources in the miniJPAS and HSC-SSP surveys (this comparison is not possible for miniJPAS-AEGIS3, given the small area of overlap between this pointing and HSC-SSP). The dashed colored lines are the completeness curves obtained from the comparison with the HSC-SSP dataset, with uncertainties highlighted by the shaded area.
