Description Before any event reconstruction, the so-called "Rejection Threshold" is used to discard data on a CCD node basis which are likely to arise from noise and which may lead to the rejection of real photons should one fall nearby and cause an unacceptable event pattern. The selection of the "Rejection Thresholds" thus requires a balance to be struck. Raising the thresholds should give a cleaner spectrum by reducing the interference of noise.

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.
