(1950s catalog of radio sources from a Mills Cross survey)
The MSH Catalog is a catalog of about 2000
radio sources published circa 1960 based on 1950s observations carried out
on the 85.5-MHz Mills Cross Radio Telescope,
a large cross-shaped array of non-steerable dipole antennas
(beamed by selecting the phases sensed) at Badgerys Creek, Australia.
The Mills Cross was successor to the Badgerys Creek 101-MHz Interferometer and was a model for
cross-style radio telescopes such as
the Mills Cross Array in Maryland.
