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.
