Redshift data for Messier Galaxies

Given below is a table of radial velocities for the Messier galaxies, taken from Nasa's Extragalactic Database (NED). Note that some of the galaxies from either the Local Group or the Virgo Cluster have negative radial velocities (blueshifts instead of redshifts). We also give positions (RA, Dec) and distances of the galaxies in this table [Warning: don't try to derive Hubble's Law from these data :-) ].
