6cm Radio Catalog
Listed in IVOA Registry (Virtual Observatory)
The NORTH6CM database is a catalog of 53,522 4.85-GHz sources generated by Becker, R. H., White, R. L., Edwards, A. L. 1991, ApJS 75, 1.
Description
It covers between 0 degrees and 75 degrees declination using observations taken with the NRAO Greenbank 300-ft telescope by Condon, Broderick and Seielstad (1989). The flux limit of the catalog is dependent on declination and ranges from approximately 40 mJy at 0 degrees to 20 mJy at 60 degrees.
The source positions given in the catalog have a 95% confidence radius of approximately 50 arcsec. Spectral indices have been calculated for 29,051 sources which have counterparts in the Texas 365-MHz Northern Sky Survey. This is a service provided by NASA HEASARC .
