  • Here's some additional information on the CO-stellar comparisons:

Stellar Dynamics

Galaxy D Mbh ML i Notes Reference
NGC315 68.1 Mpc 3.0e9+/-0.2e9 Msun F110W: 2.57+/-0.05 triaxial this work!
NGC524 23.3 Mpc 8.3(+2.7)(-1.3)e8 Msun I Band: 5.8+/-0.4 20 deg (measured from assumed to be circular disk) https://academic.oup.com/mnras/article/399/4/1839/1033212
NGC1332 22.3 Mpc 1.45e9+/-0.2e9 Msun R Band: 7.08+/-0.39 90 deg (assumed throughout, but they ran additional tests at the deprojection limit and find same Mbh/very slightly different M/L) https://academic.oup.com/mnras/article/399/4/1839/1033212?login=true
NGC4697 12.4 Mpc 2.0e8+/-0.5e8 Msun V Band: 4.3+/-0.3 90 deg (assumed throughout) there are other models in this paper; one set of models is from Gebhardt+03, the other is from this work but does not include a DM halo. the numbers quoted here are including a halo https://iopscience.iop.org/article/10.1088/0004-637X/729/1/21

CO Dynamics

Galaxy D Mbh ML i Notes Reference
NGC315 70.0 Mpc 2.39+/-0.01e9 Msun F110W: 2.06+/-0.01 74.1+/-0.1 https://iopscience.iop.org/article/10.3847/1538-4357/abd24d
NGC524 23.3 Mpc+/-2.3 Mpc 4.0(+3.5)(-2.0)e8 Msun i Band: 5.7+/-0.3 20 (fixed here) note that this galaxy initially had a huge uncertainty on the M/L in my initial version of this plot; this is because they present two models in this work, one of them fixes the incliation and the other does not. when they allow the inclination to be free, they find a strong degeneracy between M/L and i which gave very large uncertainties. i am no longer quoting this model and am instead quoting their fixed i = 20 case. https://academic.oup.com/mnras/article/485/3/4359/5371158
NGC1332 22.3 Mpc 6.64(+0.65)(-0.63)e8 Msun R Band: 7.83 85.2 deg it doesn't seem like they quote errors on anything other than the black hole mass in this work? https://iopscience.iop.org/article/10.3847/2041-8205/822/2/L28/
NGC4697 11.4+/-1.1 Mpc 1.3(+0.18)(-0.17)e8 Msun i Band: 2.14(+0.04)(-0.05) 76.1(+0.5)(-0.4) [68% conf.] https://academic.oup.com/mnras/article/468/4/4675/3574072
