Upper limits obtained for the ATCA cluster images without traces of diffuse radio emission.

Cluster name Log P1.4 GHz (WHz−1)
PSZ2 G285.63-17.23 24.46
PSZ2 G277.76-51.74 24.57
PSZ2 G286.28-38.36 24.19
PSZ2 G271.18-30.95 24.39

Notes. Thecalculated logarithm of the radio power at 1.4 GHz, by assuming a spectral index of 1.3, for the total flux density of the injected fake radio halo model in the Block3 sub-band (1.9 GHz) appears in Col. 2.
