Measurement E15M74

Experiment:	E99-105
Year:	2002	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, r_1-1⁰⁴, r₀₀¹, r₁₁¹, Re r₁₀¹, r_1-1¹, Im r₁₀², Im r_1-1², r₀₀⁵, r₁₁⁵, Re r₁₀⁵, r_1-1⁵, Im r₁₀⁶, Im r_1-1⁶. Virtual photon polarization parameter ε = 0.566. Mandelstam variable –t = 0.481 GeV². Errors include systematics, added in quadrature.
