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).
