Rotation measures of radio point sources
Listed in IVOA Registry (Virtual Observatory)
We compiled a catalog of Faraday rotation measures (RMs) for 4553 extragalactic radio point sources published in literature.
Description
These RMs were derived from multi-frequency polarization observations. The RM data are compared to those in the NRAO VLA Sky Survey (NVSS) RM catalog.
We reveal a systematic uncertainty of about 10.0+/-1.5rad/m^2^ in the NVSS RM catalog. The Galactic foreground RM is calculated through a weighted averaging method by using the compiled RM catalog together with the NVSS RM catalog, with careful consideration of uncertainties in the RM data. The data from the catalog and the interface for the Galactic foreground RM calculations are publicly available on the webpage: zmtt.bao.ac.cn/RM/ .
