Example of a galaxy model analyzed in our test. (a) Intrinsic surface brightness distribution of the bulge. (b) Galaxy bulge plus disk surface brightness distribution convolved by PSF. (b) “RMS” velocity $(V_{\mathrm{RMS}}\equiv \sqrt{{\sigma }_V^2+V^2})$ map. (c) Line-of-sight velocity field. (d) Velocity dispersion map. In all panels, the magenta dashed curve shows the bulge half-light radius. We apply the color scale in panels (a) and (b). The galaxy kinematics obtained from JAMPY (Cappellari 2008).
