Query: Radiative corrections to the lepton current in unpolarized elastic
  $lp$-interaction for fixed $Q^2$ and scattering angle   The kinematical difference between the description of radiative effects for
fixed $Q^2$ vs a fixed scattering angle in the elastic lepton-proton
($lp$)-scattering is discussed. The technique of calculation as well as
explicit expressions for radiative corrections to the lepton current in
unpolarized elastic $lp$-scattering for these two cases are presented without
using an ultrarelativistic approximation. A comparative numerical analysis
within kinematic conditions of Jefferson Lab measurements and MUSE experiment
in PSI is performed.
