As Fig. 12, but this time the fitted V_rms map is that of the GCMS data, f_DM(6 kpc) (f_DM(1.5 R_e)) is a free parameter and the central black hole mass is fixed to M_BH = 4.70 × 10⁹ M_⊙ (fit cA2). As in Fig. 2, the V_rms maps are displayed in their interpolated (left) and individual-fibre (right) forms. They surface brightness contours correspond to HST data for the interpolated maps and to photometry derived from the CGMS data for the non-interpolated ones.
