Best-fit relation between the GNN and true masses for different cases considered in Sect. 4.5.

Case	$M_{500}^{GNN} = A \times M_{500}^{True} + B \times 10^{14} M_{⊙}$ ${\textrm M}^{\text{GNN}}_{500} = \mathrm{A} \times {\textrm M}^{\text{True}}_{500} + \mathrm{B} \times 10^{14} \, {\textrm M}_\odot$
