Fig. 3.
Surface brightness profiles for our sample of MaNGA galaxies. The points denote the observed profile. The line indicates the fit by a broken exponential profile for the disc and by a general Sérsic profile for the bulge. The lower OX axis marks the fractional galactocentric distance normalized to the optical radius, Rg = R/R25. The upper OX axis shows the galactocentric distance expressed in kiloparsecs.
