Abstract: Temperature, density and abundance profiles of the hot intracluster mediumICM are important diagnostics of the complex interactions of gravitationaland feedback processes in the cores of galaxy clusters. Deprojection of X-raydata by methods such as projct, which are model dependent, can produce largeand unphysical oscillating temperature profiles. Here we validate adeprojection routine, Direct Spectral Deprojection DSDeproj; Sanders and Fabian2007, showing that it solves some of the issues inherent to model-dependentdeprojection routines. DSDeproj is a model-independent approach, assuming onlyspherical symmetry, which subtracts projected spectra from each successiveannulus to produce a set of deprojected spectra.
