Spectral fit of MOS1+MOS2 (light blue and green points) and pn (purple points) data for ObsID 0148990101 (upper left panel), 0900280101 (upper right panel), 0900280201 (lower left panel) and all stacked spectra (lower right panel). Residuals are shown in the bottom panel. The model used for fitting is the combination of cie and the isobaric CF split into three temperature intervals. The model components are represented with different colors and line styles in the plots. Orange lines represent the cie component, and blue lines represent the power law component describing the ICM and AGN, respectively. Magenta, gold, and light green lines represent the three temperature bins (0.5-1, 1-2, and 2-3 keV) components.
