Mass–radio power diagram. Left: mass–radio power diagram for radio halos (black points) and candidate radio halos (blue squares) above the 50% Planck completeness. The solid line and the shadowed region represent the correlation to radio halos only obtained with the BCES Y|X method and the 95% confidence region. The dashed line is the correlation obtained considering also candidate radio halos. The black dotted line is obtained fitting only radio halos with LIRA. Right: mass–radio power diagram for clusters with radio halos and upper limits with 0.06 < z < 0.4 and 100 kpc < r_e < 400 kpc. The solid line and the shadowed region represent the correlation obtained with the BCES Y|X method and the 95% confidence region, while the dotted black line is obtained with LIRA.
