Multi-component decompositions of the major-axis surface brightness profiles (black dots) of the Sérsic LeMMINGs galaxies in our sample without a large-scale Gaussian ring component (see Table B.2; galaxies with a large-scale Gaussian ring component are shown in Fig. D.2, whereas core-Sérsic galaxies are in Fig. D.3). The residual profiles along with the rms residual Δ for each fit are shown. The ellipticity, position angle (P.A., measured in degrees from north to east), and isophote shape parameter (B₄) profiles (red boxes) are given in the lower panels. The HST filter associated with each galaxy profile is listed in Table B.2. The surface brightnesses (μ) are in units of mag arcsec⁻². The dashed red curves represent the bulges, while the dotted blue curve shows the large-scale discs or stellar halo light which we model with an exponential function. Nuclear components (i.e. AGN, NSCs, inner discs, and bars) were typically fit with the two-parameter Gaussian model (dash-dot-dot-dot green curve). ‘SNucleus’ (‘SNuc’) (dot-dashed green curve) and ‘SDisc’ (dot-dashed blue curve) denote nuclei and large-scale disc components that were fitted with Sérsic models, respectively. Galaxy components such as bars, small-scale discs, rings, spirals, and lenses are described by Sérsic models (i.e. orange and magenta dot-dashed curves). For two galaxies in our sample (IC 239 and IC 520) their spiral arm components were modelled with a Sérsic model (i.e. ‘SSarm’). The complete fits (solid orange curves) fit the observed galaxy profiles with a median rms residual Δ∼ 0.065 mag arcsec⁻². We fit up to six model components which are summed up to a full model with (up to) 16 free parameters.
