Fig. 8.
Left: spectral index map from L- and X-band images. Right: corresponding uncertainties of the spectral index map. The contours show the X-band image smoothed to the L-band resolution and they are drawn at [ − 1, 1, 2, 4, 8, ...]× 4σrms, where σrms = 2.6 μJy beam−1. The beam is shown in the bottom-left corner.
