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.
