TitleHI line studies of galaxies. III. Distance moduli of 822 disk galaxies.
AuthorsBottinelli, L.; Gouguenheim, L.; Paturel, G.; de Vaucouleurs, G.

AbstractThe distance scale established on the basis of a distance moduli catalog (for 822 galaxies) that was derived from 21-cm line widths via the B-band Tully-Fisher relation is compared with several independent scales having a common zero point, that are based on the indicators for luminosity index, redshift, ring diameters, brightest superassociations, and effective diameters. These are in excellent systematic agreement, and confirm the linearity of the H I scale in the 24-35 modulus interval, but indicate a small systematic zero point difference of about 0.2 mag, which must be added to the H I moduli to place them on the same 'short' distance scale defined by the others.
