An Etymological Dictionary of Astronomy and Astrophysics

A catalog of 397 radio sources between declinations +20° and +27° which were compiled from a finding survey made at 635 MHz with the 64m radio telescope at the Australian National Radio Astronomy Observatory, Parkes, N.S.W. and published in 1968. Originally abbreviated PSR, this catalog, which is also called PKS,
replaces and improves on four earlier lists (1964 to 1966).
