Log intensity-coded MGCLS spectral index map of the 3C40A and 3C40B radio sources in Abell 194, at full resolution (7.7″ × 7.5″). Colours indicate the spectral index, and the brightness indicates the Stokes-I intensity. The colour bar indicates the spectral indices, with the upper (lower) part of the colour bar corresponding to the brighter (fainter) regions. The brightness is on a linear scale and saturates at 8 mJy beam−1.
