The calculation is based on PCAC masses extracted from $N_\\mathrm{f}=2+1$ flavour gauge field ensembles at five different lattice spacings in a range from 0.087 fm down to 0.039 fm. The lattice action consists of the $\\mathrm{O}(a)$ improved Wilson-clover action and a tree-level improved Symanzik gauge action. Quark masses are non-perturbatively $\\mathrm{O}(a)$ improved employing the Symanzik-counterterms available for this discretisation of QCD.
