20″ spectral index map from 1455−4700 MHz made with the VLA images. The local rms noise, σrms, in the 1455 MHz image is 80 μJy beam−1 and in the 4700 MHz image is 40 μJy beam−1. The contours mark the 4700 MHz emission at levels (3, 5, 10, 15, 20, 50)×σrms. The inset map shows the spectral index error.
