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