Galaxy (projected) circular velocity profiles used here: the solid lines correspond to the results from MGEFit, each one with its respective model indicated in the legend; the dashed lines are Keplerian profiles as originated from a SMBH with masses of 3.22 × 10⁹ M_⊙ (red line) and 4.33 × 10⁹ M_⊙ (blue line); the vertical dotted lines are (from left to right) the ALMA pixel size ($0\stackrel{″}{.}03$), HST/WFC3 pixel size ($0\stackrel{″}{.}128$), and CO disk size (∼5″).
