Description

We present an update of the scale setting for $N_f=2+1$ flavor QCD using gradient flow scales and pseudoscalar 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 $t_0,\;w_0$ and $t_0/w_0^2$ with input taken from $f_\pi$ as well as from $f_K+f_\pi/2$.
