Properties of the radio halo and relic in A754.

Source	LLS	S_0.82	S_1.28	α	P_1.4
	(Mpc)	(mJy)	(mJy)		(W Hz⁻¹)
Halo	1.6	457.8 ± 68.7	223.7 ± 11.2	1.30 ± 0.39	(1.4 ± 0.1) × 10²⁴
Relic	1.6	21.8 ± 3.4	12.5 ± 1.0	1.24 ± 0.39	(8.0 ± 0.7) × 10²²

Notes. Reported quantities are largest linear size (LLS), flux densities at 819 MHz (S _0.82) and 1.28 GHz (S _1.28), spectral index derived from images with common inner uv cut (α), and k-corrected radio power extrapolated at 1.4 GHz (P_1.4).
