Description CAL- We observe the SEP region stellar cluster at a number of occasions (5 are included as placeholders) in order to measure the changes in EPIC boresight as a function of mission elapsed time, slew leg lengths, post-eclipse conditions, solar aspect angle and other variables thought to contribute secular changes to the EPIC boresight. A modest exposure of 10ks is sufficient to centroid the brightest handful of X-rays sources with high precision. Comparison with ROSAT observations and achival optical data allows to obtain sub-pixel location accuracy.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
