| Description |
The catalogue is compiled from all groups of overlapping public XMM-Newton observations and provides information on source positions and source parameters like fluxes in the XMM-Newton standard energy bands, hardness ratios, quality estimate, and information on inter-observation variability. The catalogue contains 427 524 unique sources, 329 972 of them multiply observed. The parameters are directly derived from the simultaneous fit, and, wherever applicable, additionally calculated for each contributing observation. For lower-quality exposures, not used in source detection to ensure the detection quality, the source parameters are derived from subsequent PSF photometry. The catalogue aims at exploring the multiply observed sky regions and exploit their survey potential, in particular to study the long-term behaviour of X-ray emitting sources. It thus makes use of the longer effective exposure observed sky areas and offers the opportunity to investigate flux variability directly through the source detection process.

| Mission description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) is ESA’s flagship of high-energy astronomy. Launched by an Ariane 504 on December 10th 1999, it 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 and a long baseline for multiwavelength timing analysis. 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 looks deep into galaxy centres, studies stars at all stages of their lives, follows up on explosive events, investigates what happens around black holes and in this way allows us to learn how the Universe was formed and evolved, and how matter behaves under the most extreme conditions. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
