Distance calculated using a Hubble constant of 73~km~s$^{-1}$~Mpc$^{-1}$, and taking the influence of the Virgo Cluster, the Great Attractor, and the Shapley supercluster into account. \\ $^{{a}}$ Absorption coefficient in the $B$~band, from \cite{Schlegel1998}. \\ $^{{b}}$ $B$- and $R$-band integrated magnitudes, their $1\sigma$~uncertainty and integrated \Ha~flux, corrected for Galactic extinction \citep{GildePaz2003}. \\ $^{{c}}$ Absolute magnitude in the $B$ band, computed from the above tabulated $B$ integrated magnitude and distance. \\ $^{{d}}$ Total magnitudes from 2MASS. \\ $^{{e}}$ Neutral hydrogen mass $M_{\rm HI}$ from \cite{VanZee2001}, who adopted a distance of 10.8~Mpc. \end{table}
