摘要：

We determine the nucleon electromagnetic form factors and their uncertainties from world electron scattering data. The analysis incorporates two-photon exchange corrections, constraints on the low-Q(2) and high-Q(2) behavior, and additional uncertainties to account for tensions between different data sets and uncertainties in radiative corrections.
