Mean μ_NUV (left) and μ_FUV (right) 1D profiles as a function of galactocentric radius for different subsamples defined as a function of the total stellar mass (in bins of 0.5 dex; see legend) (see also Bouquin et al. 2018). Error bars correspond to the standard deviation of the mean (). The dashed lines show the average luminosity profiles where the radial sample coverage is greater than 75% and lower than 100%, and thus where uncertainties are larger (e.g., artificially created up-bending sections due to dominance of more extended UV disks with fainter extrapolated central surface brightnesses).
