Spectral index map of G 350.0-2.0 made from the 1.4 GHz map in Gaensler (1998) and the GLEAM 200 MHz map (Hurley-Walker et al. 2019). The overlaid contours are from the 88 MHz GLEAM image of G 350.0-2.0 (Hurley-Walker et al. 2019). The visibilities are not uv-matched, nor have the point sources been subtracted, but both images are sensitive to all scales of emission for this source. The integrated spectral index value between these two frequencies is α = −0.4.
