Axial and vector form factor are equal between Q2=13 GeV2  for F1, F2 and  16 GeV2 F3  Hall A form factors constrained for Q2>4 GeV2 for Gmn (to ratio to Gmp) constrained for Q2>3.5 GeV2 for Gen (to ratio to Gep) constrianed for Q2>6 GeV2 for Gep(to ratio to Gmp)
Next: study R elastic /quasielastic  - plot sqrt(R) to get good scale 1. Raxial = 0 for elastic
Rproton > Rneutron for elastics,  R proton is purple, R neutron is yellow Rvector (green)  smaller than Rproton (purple)  for elastics The scale is 10*Q2.  Petty sure that the plot is OK for sqrt (R proton) and sqrt (R  neutron), Need to check R vector. form factors  NOTE: Breaks in curves below are from: constrained for Q2>4 GeV2 for Gmn (to ratio to Gmp) constrained for Q2>3.5 GeV2 for Gen (to ratio to Gep) constrianed for Q2>6 GeV2 for Gep(to ratio to Gmp)
