  NOTES  --
The centre position, morphological type and optical diameter at a surface
brightness level of~25~$B$-mag arcsec$^{-2}$ are taken from the RC3.
The inclination is derived as $\cos^{2}{i}~=~(q^2-q_0^2)/(1-q_0^2)$. The
observed axial ratio $q$ is taken from the RC3 and an intrinsic flattening of
$q_0=0.11$ (Guthrie \cite{Guthrie1992}) was assumed.
The position angle of optical major axis is taken from HyperLeda.
The heliocentric velocity derived from \hi\ data is from Vergani et~al. (\cite{Vergani2006}). 
The absolute total blue magnitude is corrected for inclination and extinction
and is taken from the~RC3.
