The respective implementation priorities of the Open and the Guaranteed time programmes have been adjusted several times since launch by the Science Working Team. At its December 2001 meeting, the Science Programme Committee (SPC) of ESA recommended to accelerate the completion of the Guaranteed Time programme.

Data Processing and Distribution status as of 30-Sep-2003

Total number of Planned Observations in Routine Phase (revs 0103-0697)	3022
Total number of Performed Observations in Routine Phase	2833
Total number of Observation Data Files generated	2804
Total number of Pipeline/Data Products sets generated and distributed	2724

Turnaround (in days) between Data acquisition and final Data Products distribution (last Quarter) Values in excess of 90 days usually indicate a problem analysing the data and/or that re-processing was required.

Publications based on XMM-Newton data

Number of publications as of 30-Sep-2003 For a complete up-to-date list of publications please check here.	376
XMM-Newton publications per quarter As "submitted to" or "published in" refereed journals, derived from astro-ph.

Please note; the large number of publications in the 1st quarter of 2001 is due to the release of the A&A special on XMM-Newton. The number of publications in the quarter at the time of issue is an underestimate.
