                      ℓ̅ 3 and ℓ̅ 4 of SU(2) chiral perturbation theory,
                      based on precise lattice data for the pion mass and decay
                      constant on ensembles generated by the Wuppertal-Budapest
                      Collaboration for QCD thermodynamics. These ensembles
                      feature 2+1 flavors of two-fold stout-smeared dynamical
                      staggered fermions combined with Symanzik glue, with pion
                      masses varying from 135 to 435 MeV, lattice scales between
                      0.7 and 2.0 GeV, while ms is kept fixed at its physical
                      value. Moderate taste splittings and the scale being set
                      through the pion decay constant allow us to restrict
                      ourselves to the taste pseudoscalar state and to use
                      formulas from continuum chiral perturbation theory. Finally,
                      by dropping the data points near 135 MeV from the fits, we
                      can explore the range of pion masses that is needed in SU(2)
                      chiral perturbation theory to reliably extrapolate to the
                      physical point.},
