eROSITA 0.2−3 keV image of the shadow cast by Cha II & III. The left panel shows the eROSITA 0.2−3 keV band image of Cha II & III colour-coded with the vignetting-corrected count rate. The grey rectangular box indicates the region shown in the middle and right plots. The middle panel shows the point-source-fřee region where spectral analysis is carried out. The two rectangular mosaics represent the region covered by the Herschel column density map. The right panel shows the four column density bins that define the regions for spectral extraction. The dotted grid is in the Galactic coordinate system.
