Notes. Columns (a)–(c) are for the dynamical models when allowing the black hole component to be free, fixed and none, respectively. Rows 1–6: fitted parameters from the dynamical modeling in Sect. 4.4. They are the black hole mass, the stellar mass, the effective radius of the stellar component, the Sérsic index of the stellar component, the dark matter mass, and the CO-to-gas mass conversion factor, respectively. Row 7: the gas mass (
). Row 8: the baryonic mass (Mbary = Mstar + Mgas). Row 9: gas mass fraction (fgas = Mgas/Mbary). Rows 10–11: the virial velocity and virial radius of the dark matter halo.
The black hole mass is fixed to the value of 1.8 × 109 M⊙ (Feruglio et al. 2018).
