Table 5:

Parameters of the halo and the relics derived from the full resolution maps.
Source	Wavelength	Angular size	Flux
		( $^{\prime}$ )	(mJy)
	25 cm	7 $\times$ 4	44 $\pm$ 1^a
halo	85 cm	17 $\times$ 15	496 $\pm$ 7^a
	2 m	(17 $\times$ 15)^b	805 $\pm$ 40^a
	25 cm	11 $\times$ 3	30 $\pm$ 1
NE relic	85 cm	15 $\times$ 4	117 $\pm$ 2
	2 m	(15 $\times$ 4)^b	287 $\pm$ 17
NW relic	85 cm	21 $\times$ 1	61 $\pm$ 1
SW relic	85 cm	13 $\times$ 1	17 $\pm$ 1

^a The fluxes have been determined avoiding the radio galaxies.
^b Assumed to be the same as at 85 cm. The low resolution of the 2 m map prevented a more precise determination of this parameter.
