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