Radio power at 150 MHz vs cluster mass (M₅₀₀). The clusters with a cluster-scale halo in our sample are indicated in red, while the upper limits we derived for the other clusters in the sample are indicated with orange arrows. RHs in Planck clusters in LoTSS-DR2 (Botteon et al. 2022a) are indicated in blue and their upper limits (Bruno et al. 2023b) in cyan. The black line indicates the correlation found by Cuciti et al. (2023), using a BCES Y|X regression method, while the shaded region shows the associated 3σ region.
