KUEHR - Extragalactic Radio Sources

HEASARC
Archive

Overview

This catalog is a compilation of 518 extragalactic radio sources with flux densities greater than 1 Jy at 5 GHz. 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.

Codes AA through BL denote positions measured with radio interferometry. Codes SA through SP denote positions measured with original survey instrument.

RA
The Right Ascension of the source.

Redshift
Redshift from Veron and Veron (1979) and Kuehr (1980).

Ref_Number
Code number for the radio source catalog from which the particular flux density measurement came. The key to the reference number code is available from the HEASARC. The reference number suffix is associated with source catalog code number 94 which has three distinct catalogs associated with it and which are differentiated by either a blank space or letters "A" or "B". The key to the reference number/suffix code is available from the HEASARC.

Ref_Number_Suffix
Suffix on Reference Number

Spectral_Index
Two-point spectral index as determined between 2700 MHz and 5000 MHz. The spectral index is defined as b, where flux density is assumed proportional to v^b. Spectral index error is the associated error.

Spectral_Index_Error
The uncertainty in the spectral index.

Vmag
Visual magnitude from Veron and Veron (1979) and Kuehr (1980).
