    elastic analysis, part 1

    quick + dirty elastic analysis to check sign flip and order of magnitude of raw asymmetry:

    (after cuts 600k total good events each run, 0.1% rel stat)
    run target BHWP data expect
    2422 0 deg OUT +0.16% +0.28%
    2426 0 deg IN -0.24% -0.28%
    2446 180 deg IN +0.39% +0.28%
    2447 180 deg OUT -0.27% -0.28%

    = 0.265%
    = 0.095% (abs) (36% relative)

    my next pass will include correction for livetime asym, correction for charge asym, correction for N2 dilution, target pol, beam pol, elastic cross section, and a look at all the runs.
