|Title||The absolute flux calibration of the OM|
|Author||Mr Fred Jansen XMM-Newton PS|
|Description||We propose to observe one or more stars of each spectral type O,B, A< F, G, K, M with the optical and UV grisms as well as the U, V, V, UVW1, UVM2, UVW2. filters. The first goal of the colour calibration observations will be to refine the spectral coefficients used in the count rate to flux calculations. However, the observations will also provide data for a longer term strategy to introduce colour correction terms that can be applied to fluxes calculated from countrates received by two or more filters (i.e. B-V, UVW1-UVW2).|

|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.
