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 31-Dec-2003

Total number of Planned Observations in Routine Phase (revs 0103-0743) 3237
Total number of Performed Observations in Routine Phase 3041
Total number of Observation Data Files generated 2974
Total number of Pipeline/Data Products sets generated and distributed 2883

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. 		Data production delay

XMM-Newton publications per quarter
As "submitted to" or "published in" refereed journals, derived from astro-ph.
Total publications as of 31-Dec-2003; 436 		XMM-Newton publications per quarter
Please note; the large number of publications in the 1st quarter of 2001 is due to the release of the A&A special issue on XMM-Newton. The number of publications in the quarter at the time of issue is an underestimate.
