VizieR Online Data Catalog: Concordance fluxes; calibration X-Ray telescopes (Marshall+, 2021)

We select a sample of X-ray sources from the Second European Photon Imaging Camera (EPIC) Serendipitous Source (2XMM) Catalog. EPIC consists of three X-ray cameras with CCD sensors mounted on the ESA spacecraft XMM-Newton; the EPIC-pn and two EPIC-MOS cameras observe celestial sources quasi-simultaneously within their co-aligned fields of view. Another set of EPIC spectra used to validate the model is the XCAL sample. This is a sample of radio-loud active galactic nuclei, primarily blazars, observed routinely by XMM-Newton in the framework of its in-flight calibration program. In this case, there are more blazars and high signal observations, for a total of 108, 103, and 94 observations of 22 distinct sources in the soft, medium, and hard bands that exceeded a flux limit criterion without highly discrepant fluxes between the three instruments.
