Abstract
Using e + e- annihilation data taken at the CESR collider with the CLEO-c detector, measurements of hyperon pair production cross sections and elastic and transition electromagnetic form factors have been made at the charmonium resonances: {equation presented} and {equation presented}. Results with good statistical precision are obtained with high efficiency particle identification. Systematics of pair production cross sections, and form factors with respect to the number of strange quarks in the hyperons are studied, and evidence is presented for effects of diquark correlations in comparative results for Λ0 and Σ0, both of which have the same uds quark content but different isospin.

I wish to acknowledge the help of Mr. Luke Robison in the preparation of the manuscript of my talk for the BEACH 2018 proceedings. This investigation was done using CLEO data, and as members of the former CLEO Collaboration we thank it for this privilege. This research was supported by the U.S. Department of Energy.
