(a) Exposure-corrected, background-subtracted, Gaussian-smoothed image of Abell 4059 in the 0.5–7.0 keV energy band. The sectors used to extract the ICM spectra (green) and the masked regions (blue) are overlaid. (b) Exposure-corrected, background-subtracted, Gaussian-smoothed image of JO194 in the 0.5–7.0 keV energy band with on top the regions used for the spectral extraction based on the contours of the Hα emission and the stellar disk. The three blue sources are background galaxies, according to their MUSE optical spectra. Therefore, we exclude them from the analysis.
