Radio continuum images of the Exemplar: a) from the TGSS ADR1 at 150 MHz; b) from the GMRT at 610 MHz; c) from the NVSS at 1.4 GHz; d) from FIRST at 1.4 GHz. The size of the synthesized beam is indicated in the bottom left corner of each image. The position of the BCG is shown by a yellow cross. The circles and ellipses overlaid on the FIRST 1.4 GHz image show the regions used for the photometry and the spectral index measurements (see Tables 3 and 4). The NW aperture is a circle with a radius of 25′′, centered at (32.°49747, −5.°46036). The aperture in the central region (C) is a circle with a radius of 35′′, centered at (32.°51157, −5. °46863). The SE circular aperture has a radius of 30′′, centered at (32. °52672, −5. °47796). The ellipse (T) has a semimajor axis of 2′, a semiminor axis of 1′, and a position angle of + 125° measured counterclockwise from the north, centered at (32. °51357, −5. °46929). The position of S1 is (32. °53811, −5. °47619) and that of S2 is (32. °51574, −5. °46446) and the circles have a radius of 10′′.
