PV- X-rays from sources outside the field of view can enter the EPIC field of view. The X-ray baffles in front still leak at some level out to off-axis anglesof about 1.5 degrees. The angular dependence and the level have been measured onground but need to be verified in orbit by one pointing with the source on-axisand four additional pointings with the source offset by 70 arcmin at fourdifferent azimuth angles. The source should be sufficiently bright, stable intime and should show emission lines to ease the analysis of the spectraldependence. A moderate spatial extent but less than the EPIC field of view isadvantageous. Such a source is the Tycho SNR. This proposal is for the on-axisposition of the programme.

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.
