The 3XMM-DR7s catalogue of serendipitous sources from overlapping XMM-Newton observations

A  new  XMM-Newton  EPIC  Serendipitous  Source Catalogue made from stacking individual observations has been released.

The stacked catalogue 3XMM-DR7s has been compiled from 434 groups, comprising 1 789 overlapping good-quality XMM-Newton observations. They were selected from the public observations taken between 2000 February 3 and 2016 December 15, which were used to generate the catalogue 3XMM-DR7. It contains 71 951 unique sources with positions and source parameters like fluxes in the XMM-Newton standard energy bands, hardness ratios, quality estimate, and information on inter-observation variability.

The catalogue aims at exploring the multiply observed sky regions and exploits their survey potential.
