Query: Comment on "High-Precision Determination of the Electric and Magnetic
  Form Factors of the Proton"   In a recent Letter, Bernauer, et al. present fits to the proton
electromagnetic form factors, GEp(Q^2) and GMp(Q^2), along with extracted
proton charge and magnetization radii based on large set of new, high
statistical precision (<0.2%) cross section measurements. The Coulomb
corrections they apply differ dramatically from more modern and complete
calculations, implying significant error in their final results.
