Fig. 7.


Left: spectral index map from our reprocessed GMRT data at 610 MHz to our LOFAR HBA data at 150 MHz. Both maps are at a resolution of 6″ × 6″. Contours start at five times the rms noise (90 μJy beam−1 for both LOFAR and GMRT), and increase by a factor of 1.7. Right: corresponding spectral index error map for each pixel.
