Paper Abstract

We describe in-orbit measurements of the mirror vignetting in the XMM-Newton Observatory, using observations of SNR G21.5-09 with the EPIC imaging cameras. The instrument features that complicate these measurements are briefly described. We show the spatial and energy dependences of measured vignetting, outlining assumptions made in deriving the eventual agreement between theory and measurement. Alternate methods to confirm these are described. We briefly describe an analysis of the stray-light rejection of the telescope.
