MELA_ALL predictions of the central total mass, M_tot(r_1/2), for the real galaxy dynamical samples. The optimal feature combination (i.e., r_1/2, M_⋆ and σ) is used, as discussed in Sect. 4.1 and Table 4. Shown (from left to right) are predictions of the SPIDER sample; the DynPop/nETG; the DynPop/LTG samples; and the DSAMI sample. The dynamical model used as representative of the MaNGA Dynpop results is the JAM_sph+generalized NFW profile (see Sect. 2.3.2). For the DSAMI sample, the red triangles represent the data points from the secondary test sample (1 kpc < r_1/2 < 2R_p). The legend provides an overview of the statistical estimators for the different samples.
