APPENDIX 2

Orbital Masses

The columns are

(1) pair number
(2) apparent magnitude on the Holmberg system, corrected for galactic extinction according to (21.5)
(3) surface brightness of the pair members in B mag / square arcsecond, calculated from (5.2). Asterisks indicate merging pairs, whose component magnitudes were assigned according to (2.11)
(4) linear diameter A25 of the galaxies in kpc, along the major axis to the standard isophote
(5) absolute magnitude of the galaxies in the Holmberg system MHoc, for a Hubble constant of 75 km / (s Mpc)
(6) projected linear separation X of the pair, kpc
(7) total pair mass in solar masses, calculated according to (2.17)
(8) ratio of orbital mass to total luminosity of both components, in solar units
