53.522 4.85GHz Sources", Ap.J. Supp. 75, 1-229, 1991 January



Description

     A catalog of 53522 4.85GHz sources between 0o and 75o declination has 
been generated from observations taken with the NRAO Green Bank 300 foot 
(91 m) telescope. The flux limit of the catalog is dependant on declination and 
ranges from "40 mJy at 0o to 20 mJy at 60o. The source positions given in the 
catalog have a 95% confidence radius of "50". Spectral indices have been 
calculated for 29051 sources which have counterparts in the Texas 365MHz 
northern sky survey.
