Notes. The celestial coordinates and morphologies are taken from NASA/IPAC Extragalactic Database (NED). The distances D with the corresponding scales are taken from Verstappen et al. (2013), which were found to be the average values of the redshift-independent distance measurements (mostly based on the Tully-Fisher relation). The apparent magnitudes m 3.6/ W 1, and the semi-major and semi-minor axes (sma and smb) are measured for the isophote of 25 mag arcsec−2. The absolute magnitudes M 3.6/ W 1 correspond to the adopted distances D and apparent magnitudes m 3.6/ W 1. For UGC 4277, we used its WISE W1 image to retrieve its magnitudes and semi-major and semi-minor axes. The inclinations of the galaxies are taken from the RT models from X97 (NGC 973), X99 (IC 2531, NGC 4013, NGC 5529, NGC 5907), and B07 (UGC 4277, NGC 4217). We note that these inclinations are used in our fitting (see Sect. 3) as a first guess. The fit values of i are given in Table 4.
