Abstract	Before any event reconstruction, the so-called Rejection Threshold is used todiscard data on a CCD node basis which are likely to arise from noise and whichmay lead to the rejection of real photons should one fall nearby and cause anunacceptable event pattern. The selection of the Rejection Thresholds thusrequires a balance to be struck. Raising the thresholds should give a cleanerspectrum by reducing the interference of noise.

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.
