Abstract:
In this paper, we derive scaling relations between photometric
observable quantities and disc galaxy rotation velocity Vrot or
Tully-Fisher relations (TFRs). Our methodology is dictated by our
purpose of obtaining purely photometric, minimal-scatter estimators of
Vrot applicable to large galaxy samples from imaging surveys. To
achieve this goal, we have constructed a sample of 189 disc galaxies
at redshifts z<0.1 with long-slit Hα spectroscopy from Pizagno
et al. (2007, Cat. J/AJ/134/945) and new observations. By
construction, this sample is a fair subsample of a large, well-defined
parent disc sample of ∼170000 galaxies selected from the Sloan Digital
Sky Survey Data Release 7 (SDSS DR7).
