Description
To perform high precision calculations in lattice QCD for observables of physical interest, it is important to determine the lattice spacing with high accuracy. A convenient choice for scale setting is the observable $w_0$ which is based on the Wilson flow. However the value of $w_0$ is not determined experimentally and therefore the value of $w_0$ in physical units has to be be computed by lattice simulations before it can be used to set the scale in subsequent
calculations. We present a lattice calculation aiming to determine $w_0$ with high precision. It takes QED effects beyond quenched approximations into account.
