Query: Pseudoscalar Meson Electroproduction Above the Resonance Region   One principal motivation for studying exclusive reactions is that they
provide a new class of observables, called off-diagonal parton distributions,
for the internal structure of the nucleon. The study of exclusive reactions
provides a probe of nucleon structure complementary to purely inclusive
studies. The simplest, and possibly the most promising, type of experiment is
exclusive electroproduction of pseudoscalar mesons at small t, and at large Q2
and W.
  We show that using the CLAS spectrometer at JLAB and with beam energies
between 4 and 6 GeV, we can obtain good quality electroproduction data that
will improve our understanding of nucleon structure.
