Two examples of the radio spectral index map produced matching pixel-by-pixel the NVSS and the TGSS maps. Left is the NVSS image, right the TGSS image, at the centre we show the spectral index map: | Two examples of the radio spectral index map produced matching pixel-by-pixel the NVSS and the TGSS maps.
