摘要：
We present measurements of a combination of the decay constants of the light pseudoscalar mesons and the gradient flow scale t(0), which allow us to set the scale of the lattices generated by CLS with 2 + 1 flavors of nonperturbatively improved Wilson fermions. Mistunings of the quark masses are corrected for by measuring the derivatives of observables with respect to the bare quark masses.
