Summary and To do • Summary • xt for 52Cr • 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 • 12ΛB p-shell • Angular component tuning with Λ and Σ0 (and 7ΛHe g.s.) • 12ΛB g.s. ( and p-shell ) from the polyethylene target • 10ΛBe g.s. , 7ΛHe g.s.
