Figure 3. Conceptual diagram showing the spectral fitting technique for observational data of supernova remnant Cassiopeia A. The right panel shows an analyzed X-ray energy spectrum (note: this is a simplified version of an actual analysis process, carried out to provide a background explanation to this study). In a proper analysis, the physical aspects of the X-ray energy spectrum are considered, and the spectral analysis is performed to identify the elemental distribution of the supernova remnant, etc.
