and N2000 show a slight overestimate of the inclinations obtained by these authors, as compared to our estimates. This would indicate that the V$_{max}$ derived by them would be expected to be lower on average than those obtained by us (and in fact, the values of V$_{max}$ derived by R1991 in particular tend to be lower than those derived in our study).

A comparison between columns 4 and 5 of Table 2, of the kinematic and photometric PA’s for the galaxies used in the T-F analysis, shows that about 1/3 of the galaxies have misalignments (greater than 10 degrees) between the kinematic and photometric axes. This may be an indication that the gas is not in equilibrium in these galaxies (HCG 10d, 16c, 19a, 88b, 89d, 91a, 91c, 96a). If that is the case, and for an example the gas is collapsing and/or there is additional dispersion, then the V$_{max}$ we compute using the rotation curve of the gas is a lower limit to the real V$_{max}$ (indicated by the total mass). In other words, the real mass of the galaxy would then be higher than what we infer from our measurements. We note that four of the six galaxies
