Title THE OM UV red leak and other NRCO

Description The OM UV filters have effective wavelengths of 2910, 2310, and 2120
angstroms for UVW1, UVM2, UVW2, respectively. Some evidence has shown
that the UV filters might have a red leak which allows light outside
nominal bandpass through to the detector.
In order to get a quantitative measurement of the UV red leaks, we
need to observe one set of stars with different spectral type and
interstellar reddening. In this NRCO, we ask for 45 ks observing time
to observe 5 targets, with spectral type from O5 to M3.5 and extinction
up to Av=15.8 mag. Each requested target should be observed in all six
filters and two grisms.

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.
