Spectrum extracted from the low entropy region of MKW3s fit with a sum of 3 single temperature apec models approximating the best-fitting wdem model (see text for details). In the top panel we show the observed spectrum, the best fitting model for the p = −100 (α = 0.99) case and its breakdown into 3 components, indicated respectively in red (4.1 keV), green (3.1 keV) and blue (2.4 keV). In the bottom panel we show residuals in the form of a ratio of data over model.
