VizieR Online Data Catalog: XMM-Newton Serendipitous Source Catalogue 4XMM-DR10 (Webb+, 2022)

The 4XMM-DR10 catalogue contains source detections drawn from 11647 XMM-Newton EPIC observations, covering an energy interval from 0.2keV to 12keV. These observations were made between 2000 February 3 and 2019 December 14 and all datasets were publicly available by 2020 December 10, but not all public observations are included in this catalogue (see below for more information).

The following table gives an overview of the statistics of the catalogue in comparison with the 4XMM-DR9 catalogue.

--------------------------------------------------------------------------- 4XMM-DR10 4XMM-DR9 Increment --------------------------------------------------------------------------- Number of observations 11647 11204 443 Number of 'clean' observations 9784 9441 343 (i.e., observation class < 3) Observing interval 03-Feb-00 03-Feb-00 14-Dec-19 26-Feb-19 0.8 yr Sky coverage, taking overlaps into account ( >= 1ksec exposure) 1192 sq.deg 1152 sq.deg 40 sq.deg Number of detections 849991 810795 39196 Number of 'clean' detections (i.e., summary flag <3) 748670 713966 34704 Number of unique sources 575158 550124 25034 Number of 'cleanest' (summary flag = 0, not in high-background fields) extended detections 18093 17295 798 Number of detections with spectra 303023 288521 14502 Number of detections with timeseries 302773 288282 14491 Number of detections where probability of timeseries being constant is <1x10^-5 6972 6696 276 ---------------------------------------------------------------------------

The production and content of the 4XMM catalogue is described in the the 4XMM-DR11 User Guide at http://xmmssc.irap.omp.eu/Catalogue/\ 4XMM-DR10/4XMM-DR10_CatalogueUser_Guide.html

The slimline version of the catalogue contains one row per unique source (while the the main catalogue has one row per detection) and thus has 575158 rows. There are 45 columns, essentially those containing information about the unique sources. The catalogue also contains a column with links to the IRAP catalogue server summary pages. In the case of sources with multiple detections, the summary page of the best detection is selected (i.e., the detection with the largest exposure time, summed over all cameras), and the summary page gives cross-links to the other detections.
