This pipeline has been used for the bulk reprocessing of all available XMM observations between December 1999 (the mission start) and May 2007. The ESA XMM-Newton Science Archive (XSA) will contain the uniform set of up-to-date, high quality science products from this bulk reprocessing. The 2XMM X-ray source catalogue has been derived from a subset of these reprocessed observations.
The pipeline release note includes details of the SAS, CCF, RMF used.
Further documentation regarding this pipeline and the products generated will be added shortly.
