Description
We carry out a scale setting procedure of a mixed action setup consisting of valence Wilson twisted mass fermions at maximal twist on CLS ensembles with 𝑁𝑓=2+1 flavours of 𝑂(𝑎)-improved Wilson sea quarks. We determine the gradient flow scale 𝑡0 using pion and kaon isoQCD masses and decay constants as external input. We employ model variation techniques to probe the systematic uncertainties in the extraction of the ground state signals of lattice observables, as well as for the continuum-chiral extrapolations used to compute 𝑡0 at the physical point.
