Notes. Left: the rms of the difference in aperture and decomposition magnitudes for a range of aperture magnitude bins (black lines in Fig. 3). These can be used as the estimated uncertainties of the calculated magnitudes. Right: the mean rms for stellar mass within bins of log10(M*/M⊙), which estimates the uncertainty in stellar mass due to uncertainties in the total magnitudes (i.e. values from the left). The rms were calculated based on 1000 Monte-Carlo realisations of stellar mass for each galaxy in our sample (see Eq. (17), and the accompanying text in Sect. 5).
