Notes. (3) and (4) Projected linear separation taken from NED; (5) Absolute radial velocity difference calculated using redshift sources specified in Cols. 6 and 7; (6) and (7) References regarding the redshift sources of the primary and the companion, respectively, generally taken through NED.

(a)

We list the J2000 coordinates taken from Aladin for the name of the anonymous companion.

(b)

The absolute radial velocity difference itself was taken from the source given in Col. 6.

(c)

Anomalous redshift galaxy system, not taken into account in the companion statistics.
