Multi-temperature model derived from the XMM-Newton data. a) Definition of spectral regions used to construct the multi-temperature model, b) temperature map obtained from the XMM-Newton spectral analysis, c) and best-fit multi-temperature model. Panel a) shows the central 25 grids (1 grid = 2′ × 2′) and the surrounding region within a circle of r = 10′. In panel b), the color scale indicates the gas temperature in keV, ranging from 5 (navy) to 25 (white). Panel c) shows the total model (solid line) as well as the APEC models for the 26 spectral regions within r < 10′ (the dashed lines).
