CAL- we will observe the Crab-like SNR 3C58 to measure the spectrum to revealdepartures from a simple power-law fit that may be caused by groundcalibration inaccuracies. This object is not subject to pile-up effects so that we can be sure that spectral residuals will be more likely due to calibrationerrors in the response matrices. In addition, offset pointings are made tomeasure the energy dependent vignetting (in y direction to ensure we miss abright star on the planned dates). Epic overheads of 4 ksec per exposure havebeen assumed.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
