Spokespersons: M. Garçon, M. Guidal, E. S. Smith
Measurement comment: Omega spin matrix elements from method of moments, background unsubtracted. Data were integrated up to t' = t0 - t < 0.5 GeV2. The abscissa (arguments n = 1 - 15) corresponds to the following list of matrix elements: r0004, Re r1004, r1-104, r001, r111, Re r101, r1-11, Im r102, Im r1-12, r005, r115, Re r105, r1-15, Im r106, Im r1-16. Virtual photon polarization parameter ε = 0.566. Mandelstam variable –t = 0.481 GeV2. Errors include systematics, added in quadrature.
