IC spectra of the whole remnant, based on parameters related to different parts of the shell. The spectra for those regions are shown by the following lines: S by solid line, SE region by dotted line, SW by dashed line, NE by dot-dashed line, and NW by long-dashed-dotted line. The spectra for SE and SW are overlapping. The parameters for radio emitting electrons are α = 2.54, γ_max  =  3.2 × 10⁷.
