Abstract

We present measurements of a combination of the decay constants of the light pseudoscalar mesons and the gradient flow scale $t_0$ , which allow to set the scale of the lattices generated by CLS with $2 + 1$ flavors of non-perturbatively improved Wilson fermions. Mistunings of the quark masses are corrected for by measuring the derivatives of observables with respect to the bare quark masses.
