From Wikipedia:


The RCW Catalogue (Rodgers, Campbell, Whiteoak) is an Astronomical catalogue of Hα-emission regions in the southern Milky Way, described in (Rodgers et al. 1960). It has 180 objects and includes many of the earlier Gum Catalog (84 items) objects, and the later Caldwell catalogue included some RCW.

The Catalogue was compiled by Alexander William Rodgers, Colin T. Campbell and John Bartlett Whiteoak, who led by Bart Bok, catalogued southern nebulae while working at the Mount Stromlo Observatory in Australia in the 1960s.
