We analyze two gauge ensembles with the Wilson-clover fermion action, a lattice spacing of $a\\approx 0.09$~fm and pion masses $m_\\pi\\approx 170$~MeV and $m_\\pi\\approx 280$~MeV. In our analysis we employ momentum smearing as well as a set of techniques to investigate excited state effects. Good agreement with experiment and phenomenology is found for the ratios $G_E/G_M$ and $F_2/F_1$, whereas discrepancies are observed for the individual form factors $F_1$ and $F_2$.
