Description A series of non-routine calibration observations is requested in order to convert count rates to flux according to spectral type on the XMM-OM. We have observed seven targets varying in spectral type from O5V to M2V (NRCO #32) in order to calculate a count rate to flux ratio. The OM calibration team believes that it is important to observe more stars of each spectral type to reduce the statistical errors. We have checked no duplication with the AO3 observations.

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.
