All-sky 4.85 GHz flux measurements of H II regions

We present an all-sky flux catalog of 760 H II regions with angular sizes ranging up to 10' at 4.85 GHz. The data were compiled in a self-consistent manner from existing images of the Green Bank and Parkes-MIT-NRAO 4.85 GHz 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 that 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, which is within the formal uncertainties of these values.
