Same as Fig. 3 but with contours overlaid that depict radio emission detected by the MWA and regions of spectral extraction indicated and labeled. The contour levels correspond to 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.10, 0.11, 0.12, 0.13, 0.14, 0.15, 0.155, and 0.16 Jy beam⁻¹. The X-ray emission along the eastern and western rims of G5.9+3.1 appears to lie interior to the radio rims, while X-ray and radio emission from the northern and southern rims are weak or absent. The source regions of spectral extraction for the northern, western, and eastern rims along with the entire SNR are indicated, as well as the accompanying regions of background spectral extraction.
