| Abstract | We propose to re-observe G21.5-00.9 on 9 raster positions, covering the fullrange of off-axis angles from 0 to 13 arcmin, and carefully selecting theregions on both MOS2 and PN, with no chip gaps and bad columns. We shall coverall MOS2 CCDs and in addition we add 3 more raster points in the central one.Based on the previous observations, using an exposure time of 10 ks perobservation, we shall achieve excellent statistics: expected 4000 counts in thehard band 2-10 keV, sufficient to allow derivation of the vignetting withsmall uncertainties. G21.5-00.9 has an excellent visibility for full revolutions in March-April2021, thus all 9 rasters could fit into one revolution. |

| 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. |
