Abstract:
    We present an all-sky flux catalog of 760 H II regions with angular
    sizes ranging up to 10' at 4.85GHz. The data were compiled in a
    self-consistent manner from existing images of the Green Bank and
    Parkes-MIT-NRAO 4.85GHz radio continuum surveys. Nearly 35% of these
    H II regions have fluxes measured from these surveys for the first
    time. We compared our results to the previously published source
    catalogs which fit the same data. The new flux measurements agree
    within 5%-7% of these values and fall well within the formal errors.
    The diameters fall within 16% of the previously published fits to the
    same data, within the formal uncertainties of these values.
