|Title||MOS redistribution off-axis and QE check -2|
|Author||Dr Arvind Parmar XMM-Newton MM|
|Description||NRCO#68: The MOS redistribution off axis is different from that on axis due to the "patch" (on-axis area of anomalous response). From 1E0102 observations off-axis this is known and currently improved in the calibration. To determine the redistribution at high energies we need an observation of a hard source. This addresses the targeted improvement of redistribution for line rich sources endorsed by the XMM-Newton UG. REJ2248 should be shifted orthogonal to the readout on the pn, keeping it on the same pn CCD, but within the MOS large window (shifted 1.5 armin but allowing the source to be extracted still within a radius of 40" arcsec).|

|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.
