Data analysis method for XMM-Newton observations of extended sources and application to bright massive clusters of galaxies at z=0.2

In this paper, a review is given of methods useful for XMM EPIC data analysis of extended sources, along with some applications to a bright massive cluster of galaxies at z=0.2, ABELL 209. This may constitute an introduction to that kind of advanced analysis, complementing cookbooks that can be found over the internet, the XMM EPIC calibration status document, and the data analysis workshops organised in VILSPA, which were only dedicated so far to point sources analysis. In addition, new spectro-imaging techniques are proposed, in order to measure for instance the intracluster medium mass and temperature profiles, or even maps.
