We present measurements of a combination of the decay constants of the light pseudoscalar mesons and the gradient flow scale t0, 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.

Abstract
We present measurements of a combination of the decay constants of the light pseudoscalar mesons and the gradient flow scale t0, 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.
