Notes. The best-fit values along with the 1σ uncertainties obtained by the DiskFit modeling. The values in square brackets have been kept fixed during fitting. The distances from Table 1 have been used. Column 3: systemic velocity. Column 4: dynamical stellar mass. Column 5: disk positional angle (PA). Column 6: disk inclination angle. Column 7: disk gas emission radius.
