12. Summary and To do Summary – xt for 52 Cr REPLAY was not done for all runs – Matrix tuning Modified  Tuning from early matrices To do – xt for 52Cr Initialization  calibration New parameters  REPLAY with a local PC ( ~1 week ) – Matrix tuning 12 Λ B p-shell Angular component tuning with Λ and Σ 0 (and 7 Λ He g.s.) 12 Λ B g.s. ( and p-shell ) from the polyethylene target 10 Λ Be g.s., 7 Λ He g.s.
