Extragalactic Radio Sources
Listed in NASA Data Portal
This catalog is a compilation of 518 extragalactic radio sources with flux densities greater than 1 Jy at 5 GHz.
Description
It contains sources from the NRAO-MPI 5-GHz Strong Source Surveys and from re-observation at 5 GHz of sources found in the Parkes 2.7-GHz surveys. All sources were found in 9.811 sr covered by the two surveys.
This is essentially the whole sky, excluding the galactic plane (latitudes less than 10 degrees) and the Magellanic Clouds. The catalog includes radio flux densities, radio positions, object classes, visual magnitudes, redshifts, and spectral indices. One duplicate entry was removed from the HEASARC implementation of this catalog in June 2019.
