If no reference is given, the distance is based on $V_{{\rm sys}}$ (Col.~4) and a Hubble flow using $H_0=75\rm {~{km}~{s}^{-1}~Mpc^{-1}}$, including a correction for Virgocentric infall \citep{mould-2000}; (6)~absolute \emph{V}-band magnitude as given in \cite{pildis-1997}, corrected to our distance estimates; (7) $V-I$ color from \cite{pildis-1997}; (8)~total \HI~mass (in units of $10^7~M_{\odot}$); (9)~uncorrected width of the \HI~profile at the 20~percent level of the maximum intensity. The values listed here for $W_{20}$\ are derived using the Hanning smoothed data; (10)~as Col.~9, but for the $W_{50}$\ profile; (11)~width of the $W_{20}$ profile, corrected for the finite velocity resolution, and turbulent motion of the \HI~gas; (12)~as Col.~11, but for the $W_{50}$\ profile; (13)~adopted inclination angle. The velocity widths in Cols.~(9)$-$(12) are not corrected for inclination effects. \end{table}
