The calculation was performed with $2+1$ flavors of domain wall fermions at lattice spacings of $a\\approx 0.11\\:{\\rm fm},\\:0.085\\:{\\rm fm}$ and pion masses in the range $230\\:{\\rm MeV} \\lesssim m_\\pi \\lesssim 350$ MeV. The form factors are extrapolated to the continuum limit and the physical pion mass using modified $z$ expansions.
