Deprojection and PSF deconvolution. Left: Surface brightness profile in the [0.7-1.2] keV band (red points). The green curve shows the best fitting multi-scale model (green curve), projected along the line of sight and convolved with the XMM-Newton PSF. The blue curve shows the model profile deconvolved from the PSF. In the bottom panel we show the residuals from the best fit model. Right: Spectroscopic temperature profile (red points) and best fitting models. The orange and green curves show the 3D model profiles from the ‘Forward’ and ‘non-parametric’ methods, respectively. The blue and cyan curves show the corresponding projected and PSF convolved models.
