VizieR Online Data Catalog: eROSITA extragalactic CalPV serendipitous catalog (Liu+, 2022)

This serendipitous survey combines 11 extragalactic fields, which target various types of astronomical objects for various purposes.

The bright AGN 3C390.3 was observed for commissioning (COM) and calibration of the ART-XC telescope; six fields were observed for calibration (CAL) purposes targeting well-known, bright X-ray sources; and the other four fields were performance verification (PV) observations designed with the scientific goals of investigating galaxy cluster (Abell 3391/3395, PI Thomas Reiprich), AGN (1H 0707-495, PI Thomas Boller), ULX (NGC 7793 P13, PI Joern Wilms), and Galactic dark cloud (TGU H2213 P1, PI Michael Freyberg).

We compile a catalog of 9515 sources detected in the 11 fields.

For each source, count rates are both measured during the source detection in the three source-detection bands (0.2-0.6, 0.6-2.3, 2.3-5keV) and during post-hoc forced photometry in the two forced-photometry bands (0.5-2, 2.3-5keV).

We identify the multiband counterparts of our X-ray sources following the counterpart identification of the eFEDS catalog (Salvato et al., 2022A&A...661A...3S, Cat. J/A+A/661/A3).
