Virtual Compton scattering (VCS) can be used to explore the structure of hadrons. In the domain of large energy and momentum transfers, VCS is complementary to deep-inelastic scattering. If the kinematics is collinear, generalized parton distributions (GPDs) are widely used to describe VCS. This formulation satisfies electromagnetic gauge invariance only approximately. We propose to analyze experimental data in terms of Coulomb form factors, which occur in a gauge invariant formulation of Compton scattering, do not depend on the kinematics and can be related to GPDs in the deeply virtual limit.
