Spectral index map of the radio halo in 1RXS J0603.3+4214 at resolution. Left: low-frequency (150 and 650 MHz) spectral index map. Contour levels are from the LOFAR and drawn at . Right: high-frequency (1.5 and 3 GHz) spectral index map. Contours are from the VLA L-band and are drawn as in the left panel. These maps confirm a remarkably uniform spectral index distribution across the halo C between 150 MHz and 3 GHz. It is evident that the relic+halo region shows spectral steeping at low frequencies while there is a uniform spectral index distribution at high frequencies. These maps were created using images IM10, IM13, IM18, and IM21 (see Table 2 for image properties). The color bar shows spectral index α.
