Description
We present a final analysis of gradient flow and the associated scale $w_0$ measured on the $N_f=2+1+1$ HISQ ensembles. Compared to previously reported results, we have improved the interpolation to physical quark masses using chiral perturbation theory, adjusted for variations in charm quark mass between ensembles, and derived a `prediction' function for estimating the scale using $w_0/a$ on new ensembles with unphysical quark masses. Additional results include a comparison of $t_0/a$ to $w_0/a$ and a test of agreement between the RHMC and RHMD generation algorithms.
