150 MHz radio halo power against cluster mass (M₅₀₀). The black data points were taken from Botteon et al. (2022a). The blue points are from Biava et al. (2024), where the emission from the mini-halo component was removed. The solid line shows the best-fit correlation using the BCES orthogonal method from Cassano et al. (2023). The magenta data point is for the combined emission from the radio halo and the mini-halo. The green point is for the giant radio halo only. The flux densities to compute the radio power came from our radial surface-brightness profile fitting (Eq. (1)), integrated out to 3r_e. For the blue data point, we simply added the individual “halo components” integrated out to their own specific 3r_e values.
