Description:
    We  present new radial velocities for 203  galaxies in 105 pairs and 2
    triplets. The  majority are close pairs  of early-type galaxies; there
    are  also pairs including a giant  spiral galaxy (generally M51 type),
    and  a few are wide pairs of early-type galaxies. Most velocities were
    measured from the absorption lines in the region of Mgb; emission-line
    velocities are also  given  for  22  galaxies.  The  velocity  of  one
    component only was measured  in  13  (generally  hierarchical)  pairs.
    Velocity  dispersions were measured for a  subsample of 18 close pairs
    of early-type galaxies.

              from the center; there is no emission in the very center of the
              galaxy.
