Fortran code for calculation of radiative corrections to exclusive
electroproduction of pions on a nucleon. Current version computes
corrections to the unpolarized coincidence cross section and beam
asymmetry (aka the fifth structure function). Distinctive features are
a) Covariant technique of cancellation of the infrared divergence leads
to independence of the parameter that splits soft and hard regions of
brem photons and
b) Integration over the brem photon phase space is exact, not relying
on the peaking approximation.
MAID and AO are used to model the reaction mechanism. The code is
extendable to any exclusive electron scattering with two-body breakup,
such as p(e,e'K)Lambda,
d(e,e'p)n, 3He(e,e'p)d, etc.
