| Abstract: | We have compiled a large sample of 3041 spiral galaxies with multi-band $gri$ photometry from the the Sloan Digital Sky Survey (SDSS) Data Release 7 archive. We compare our own extracted photometry with data products provided through the SDSS pipeline algorithms. This comparison benefits from an extensive compilation of galaxy rotational velocities, $V$, derived from HI linewidths. Galaxy sizes and luminosities can thus be compared against an unbiased and independent metric. We find the SDSS radial ($R$), and luminous, ($L$), data products to be unreliable for the construction of tight scaling relations of $R$ and $L$ with velocity ($V$). We use our own robust scaling parameters to yield the tightest $VRL$ relations possible. We further compile the largest scaling relation of galaxy baryonic mass (stars + gas) with velocity to find that the relation is not tighter, and thus no more significant, than the luminous $VL$ relation. |
