Catalog Service: Rotation measures of radio point sources
Description
We compiled a catalog of Faraday rotation measures (RMs) for 4553 extragalactic radio point sources published in literature. 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: http://zmtt.bao.ac.cn/RM/ .

This is service that does not comply with any IVOA standard but instead provides access to special capabilities specific to this resource.
This is a standard IVOA service that takes as input an ADQL or PQL query and returns tabular data.
This is a standard IVOA service that takes as input a position in the sky and a radius and returns catalog records with positions within that radius.
