Notes. Flux densities were measured from 25″ resolution images, created with uniform weighting and without any uv-cut. The regions where the flux densities were extracted are indicated in the left panel of Fig. 6. We assume an absolute flux scale uncertainty of 10% for the GMRT and LOFAR data, 4% for the VLA L-band, and 2.5% for the VLA S-, C-band data. The flux density of the halo excludes the “relic+halo” and region S; The spectral index values are obtained from images with a uv-cut; see Sect. 5; ( † )the largest linear size at 3 GHz; ( ‡ )size of the halo includes the “relic+halo” and region S.
