Effective radius - mass relation for the galaxies in our sample. The local sample corresponds to the galaxies used in Chamba et al. (2022) while the effective radius of the galaxies explored in this paper were retrieved from van der Wel et al. (2012). The galaxies are colour coded according to the size measured in this work (R_edge). The dashed lines correspond to the fitting to the local sample while the green solid lines to the fits to the higher redshift galaxies. The slope of the global fitting is left fixed to the local sample. There is a mild decrease of the effective radii with redshift, but not as steep as in the R_edge’s case. Besides, the scatter (∼0.2 dex) is ∼2 times larger than the one found using R_edge as a size indicator (∼0.1 dex).
