Notes. The best-fit central surface mass density (Σ0), the scale length (Rd), and the truncation radius (Rt) of the gaseous component can be found in Cols. 2–4. Best-fit M/L ratio (Υb) for the bulge (where applicable) and M/L ratio (Υd) for the disk are presented in the Cols. 6 and 7. The best-fit parameters of the slowly rotating BEC model are given in Cols. 9–11: the central density of the rotating BEC halo (ρc), size of the static BEC halo (ℛ), and the angular velocity of the rotating BEC halo (ω). The χ2 of the fits and the 1σ significance levels are also presented. The only galaxy that cannot be fitted within 1σ is flagged (⋆). The total masses of the gaseous (Mtot, g), the stellar (Mtot, s), and the slowly rotating BEC components (MsrBEC) are also given in Cols. 5, 8, and 12, respectively.
