| Abstract | A series of non-routine observations is requested in order to convert countrates to flux according to spectral type on the XMM-OM.The OM calibration team proposes to observe one or more stars of each spectraltype O, B, A, F, G, K and M with the optical and UV grisms as well as the U, B,V, UVW1, UVM2, UVW2 filters. The first goal of the colour calibrationobservations will be to refine the spectral coefficients used in the count rateto flux calculations. However, the observations will also provide data for alonger term strategy to introduce colour correction terms that can be applied toflux calculated from count rates received by two or more filters. |

| 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. |
