Notes. RA, Dec, heliocentric velocity, distance, scale, and Galactic extinction taken from NED (http://ned.www.ipac.caltech.edu/). The distance is calculated using a Hubble constant of 73 km s-1 Mpc-1, and taking into account the influence of the Virgo cluster, the Great Attractor, and the Shapley supercluster.
Integrated magnitudes from Gil de Paz et al. (2003), corrected for Galactic extinction;
