Mass estimation of the clusters in our sample with diffuse radio emission.

Cluster name	Cluster mass (M₅₀₀ [×10¹⁴ M_⊙])

	CARMA 30 GHz	M₅₀₀ − λ₁₅	M₅₀₀ − F_X
MOOJ0123+2545	3.9 ± 0.8	$1 . 9_{- 0.5 (- 0.4)}^{+ 0.6 (+ 0.4)}$ $1.9^{+0.6(+0.4)}_{-0.5(-0.4)}$	$1 . 9_{- 1.0}^{+ 0.7}$ $1.9^{+0.7}_{-1.0}$
MOOJ1231+6533	4.7 ± 1.1	$2 . 8_{- 0.7 (- 0.3)}^{+ 0.8 (+ 0.3)}$ $2.8^{+0.8(+0.3)}_{-0.7(-0.3)}$	$4 . 3_{- 0.5}^{+ 0.4}$ $4.3^{+0.4}_{-0.5}$

Notes. First column: cluster name. Second to fourth columns: masses obtained from the literature (CARMA observations at 30 GHz, see Decker et al. 2019, second column), from the M₅₀₀ − λ₁₅ relation calibrated with ACT clusters (Orlowski-Scherer et al. 2021, third column), and from the M₅₀₀ − F_X scaling relation from eROSITA 0.4–2.3 keV observations (Sunyaev et al. 2021; Predehl et al. 2021, fourth column).
