| Abstract: |
The 3XMM-DR4 catalogue is the third generation catalogue of serendipitous
X-ray sources from the European Space Agency's (ESA) XMM-Newton observatory,
and has been created by the XMM-Newton Survey Science Centre (SSC) on behalf
of ESA. Released in July 2013, 3XMM-DR4 contains 531261 detections
from 372728 unique sources observed in 7427 XMM-Newton observations, about
50% more than in the preceding 2XMMi-DR3 catalogue, made public in April
2010. We review some of the key science-driven algorithmic and calibration
changes to the processing pipeline adopted to enhance the scientific quality
of the catalogue, such as the optimised filtering of background flares,
improvements to the astrometric analysis and upgrades to the catalogue
construction process. Examples of the gains obtained are illustrated. |
