The calculation is performed using two flavors of dynamical clover fermions at lattice spacings between $0.060\\,\\text{fm}$ and $0.081\\,\\text{fm}$, different lattice volumes up to $m_\\pi L = 6.7$ and pion masses down to $m_\\pi=150\\,\\text{MeV}$. Bare lattice results are renormalized non-perturbatively using a variant of the RI'-MOM scheme and converted to the $\\overline{\\text{MS}}$ scheme.
