  In this paper, a review is given of methods useful for XMM-Newton 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-Newton EPIC calibration status document (Kirsch, 2002),
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.
