  We report measurements of cross sections for the reaction p(e,e'K)Y, for both
the Lambda and Sigma_0 hyperon states, at an invariant mass of W=1.84 GeV and
four-momentum transfers 0.5<Q2<2 (GeV/c)2. Data were taken for three values of
virtual photon polarization, allowing the decomposition of the cross sections
into longitudinal and transverse components. The Lambda data is a revised
analysis of prior work, whereas the Sigma_0 results have not been previously
reported.
