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 $N_f=2+1$ flavours of $O(a)$-improved Wilson sea
quarks. We determine the gradient flow scale $t_0$ 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 $t_0$ at the
physical point.
