We present an update of the scale setting for Nf = 2 + 1 flavor QCD using gradient flow scales and pseudo-scalar decay constants. We analyze the latest ensembles with 2 + 1 flavors of non-perturbatively improved Wilson fermions generated by CLS for improved precision. Special care is taken to correct for mistuning by measuring directly the mass derivatives of the various observables. We determine t0 with input taken from a combination of leptonic decay rates of the Pion and the Kaon. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0)

Abstract
We present an update of the scale setting for Nf = 2 + 1 flavor QCD using gradient flow scales and pseudo-scalar decay constants. We analyze the latest ensembles with 2 + 1 flavors of non-perturbatively improved Wilson fermions generated by CLS for improved precision. Special care is taken to correct for mistuning by measuring directly the mass derivatives of the various observables. We determine t0 with input taken from a combination of leptonic decay rates of the Pion and the Kaon. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0)
