Overview of the light and mass models used in this paper. Top: isophotes of the HST/ACS F850LP band imaging data of FCC 47 (black) overplotted with the MGE model from Sect. 3.1 (red). Middle: mass map derived by multiplying the luminosity in the HST/ACS F850LP image with the M_*, MW-IMF/L (fixed IMF) shown in the left panels of Fig. 2. Overplotted is the MGE model from Sect. 3.2 (red). Bottom: mass map derived by multiplying the luminosity in the HST/ACS F850LP image with the M_{*, free-IMF}/L (varying IMF) shown in the right panels of Fig. 2. Overplotted is the MGE model from Sect. 3.3 (red). From left to right, we show a cut-out of the central 5 × 5 arcsec that is dominated by the NSC, a zoom out to 20″ × 20″, and a zoom out to 160″ × 160″ covering the full galaxy. Masked regions are shaded in grey. Only for this visualisation, the ACS image and the MGE were rotated such that North is aligned with the y-axis.
