Best-fitting Schwarzschild model for FCC 153. The data (left), fits (middle), and residuals (right) of, from top to bottom, the dynamical model (surface brightness, velocity, velocity dispersion, and h3 − h6), and the subsequent stellar-population fitting (age and metallicity). The outline of the MUSE mosaic is shown in dashed brown. All residual panels show the absolute differences (data – model), but are offset such that green is zero. The stellar-population maps share a common colour-bar between galaxies for comparison. We note that for FCC 153, since the observed metallicity map reaches 0.4 dex along the major axis, and is itself an average through the LOS, we extend the upper bound for the individual components during the stellar-population fitting to 1.0 dex.
