Comparison between data and models. Bottom left: kinematic sample from M08. In blue (gold), we show stars included in (excluded from) our analysis. Top left: derived los velocity dispersion profile. The bins’ edges are indicated by vertical dashed lines in the bottom-left panel. The red points represent the los velocity dispersions computed from the LOSVDs shown in Fig. 2. Middle panel: marginalized velocity distribution. Top right: surface brightness profile from BR21. Bottom right: model residuals compared to the data. The light (dark) blue and red bands represent the models’ 1σ (3σ) confidence intervals, while the solid curves are median models.
