Segmentation used in this study compared to the image of Tycho’s SNR in different energy bands. The map is not corrected from the exposure map to highlight the diversity in counts across the regions. Left: Between 1.6 and 4.2 keV to highlight the IME emission (Si, S, Ar and Ca) with a bin size of 0.5” Right: Energy band between 5.8 and 7.1 keV, which represents the Fe-K emission with some contribution of the synchrotron emission with a bin size of 2” and a Gaussian smoothing with a kernel of 2”.
