Query: Analysis of Deeply Virtual Compton Scattering Data at Jefferson Lab and
  Proton Tomography   The CLAS and Hall A collaborations at Jefferson Laboratory have recently
released new results for the ep->ep{\gamma} reaction. We analyze these new data
within the Generalized Parton Distribution formalism. Employing a fitter
algorithm introduced and used in earlier works, we are able to extract from
these data new constraints on the kinematical dependence of three Compton Form
Factors. Based on experimental data, we subsequently extract the dependence of
the proton charge radius on the quarks longitudinal momentum fraction.
