Radial profiles of galaxies with stellar masses ∼10⁹ M_⊙ from the Chamba et al. (2022) field sample. Left to right: RGB composite image from IAC Stripe 82 with a grey background to highlight the low surface brightness edge location (pink ellipse). Surface brightness profiles in r-band (orange) and g-band (cyan), g − r colour and surface stellar mass density profiles. The location of the detected edges are shown as vertical dashed lines and the shaded grey areas are the typical uncertainties associated with repeated measurements by Chamba et al. (2022) (∼0.04 dex).
