[BLAST_ANAWARE] minutes analysis meeting 4/23

_ Overall succesfull meeting focussed on eep/ed data from D2 run (3/24 - 4/3)
        _ montecarlo effects important.
        _ Comparison to recon data fair. Needs study of kin corrections
        _ Extracted polarization values seem consistent
                Pz : 75 +- 4 Pzz : 49 +- 9 (from eep )
                        _ Pzz : 51 +- 4 (from T20 )

_ Some open issues for next deuterium run
        _ Missing ed events (hardware ? trigger ? )
        _ neutron timing
        _ vector ed

_ Some issues for recrunching (see dst changes)
        _ tdc offsets
        _ montecarlo reconstruction (bug in recon ?)

_ Other
        _ eg: some study of detector shifts
                _ Move detector out. Changes z not p

        _ cc: show novel method to extract Ge/Gm from combined LR data
                _ improved statistics error bar
