Parkes-MIT-NRAO Surveys

The Parkes-MIT-NRAO Surveys (PMN) are radio surveys of the southern hemisphere conducted in 1990 by the Parkes Observatory, using the NRAO Seven-beam Receiver loaned by the National Radio Astronomy Observatory (NRAO) from its usual place on the Green Bank 300ft Telescope, the "Green Bank Telescope" of the time. It is the southern hemisphere analog of the Green Bank 6-cm Radio Source Catalog. Many radio galaxies were discovered, some still are known by their "PMN" designation.
