Synchrotron spectra with the observed best-fit X-ray data for different regions of the shell. The spectral index describing radio-emitting electrons for all the regions is α = 2.54. The estimated magnetic fields for different shell regions are: 250 μG for S (solid line); 330 μG for SE (dashed line) and SW (dotted line); 410 μG for NE (dot-dashed line); 510 μG for NW (long-dash-dotted line), and 250 μG for the whole remnant (double-dot-dashed line). The best-fit X-ray fluxes of the S, SE, SW, NE, NW, and the whole remnant are shown with green, blue, magenta, cyan, brown, and black stripes.
