L_X − P_1.4 GHz (top) and M₅₀₀ − P_1.4 GHz (bottom) diagrams of radio halos. Figures are modified based on the version in van Weeren et al. (2019), where the data samples are from Cassano et al. (2013), Kale et al. (2015) and Cuciti et al. (2018). Blue points are clusters with radio halos and gray upper limits are clusters without radio halos. Blue dashed lines are the best-fit scaling relations from Cassano et al. (2013). The red triangle is ClG 0217+70 using the previous redshift, the green triangle is the corrected value. The error bars of L_X and P_1.4 GHz of ClG 0217+70 are smaller than the plot symbols.
