Experiments carried out at the Cooler Synchrotron (COSY) by the EDDA Collaboration have had a significant impact above 1 GeV. Results are discussed in terms of the partial-wave and direct-reconstruction amplitudes.16 pages, 14 figures, 2 tables; Fig 10 error corrected; Accepted for publication in Physical Review CNuclear Theorytext
