Title: Setting the scale for the CLS 2 + 1 flavor ensembles

Abstract

Here, 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. Furthermore, we correct for mistunings of the quark masses by measuring the derivatives of observables with respect to the bare quark masses.
