An optical catalog of extragalactic emission-line objects similar to quasi-stellar objects

A catalog of 935 galaxies which have optical properties similar to those of QSOs is given. A subsidiary table of cross-identifications enables the reader to relate the name of a given object to its coordinate name. Most of the objects appear to be nonstellar. The majority, more than 700, have redshifts z = 0.2 or less, and have mostly been classified as Seyfert galaxies, N systems, or radio galaxies. The Hubble diagram for all of the objects with z = 0.2 or less is shown. The redshift distribution peaks at z = 0.025, but there are about 200 powerful radio galaxies in the extended tail of the distribution which have z greater than 0.2. There is a separate and distinct peak in the redshift distribution at z = 0.06
