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 q₀=0.11 (Guthrie 1992) was assumed. The position angle of optical major axis is taken from HyperLeda. The heliocentric velocity derived from H I data is from Vergani et al. (2006). The absolute total blue magnitude is corrected for inclination and extinction and is taken from the RC3.
