    keyword=missing mass how-to

    missing mass FORTRAN is mmjr.f
    it includes mmjr.inc which defines constants and the kinematics
    (you have to change mmjr.inc for new kinematics)

    A heroic Nilanga worked until late at nite and improved the cointime calibration.
    To use his new calibration run espace_new and use the data base file db_e94194_new (Pete set this up already)

    Here follows a set of cuts which give you sort of a clean missing mass (mmjr.cuts)

    1 ND abs(dpk) < 0.1 .AND. 1
    1 ND abs(dpe) < 0.1 .AND. 1
    1 ND abs(TC_COR-260.) < 5. .AND. 1
    1 ND LAERO1 < 100. .AND. 1
    1 ND LAERO2 < 19000. .AND. 1
    1 ND LAERO2 > 300. .AND. 1
    1 ND abs(RGASSUM-5000) < 4900. .AND. 1

    with these cuts plot mmjr.f in to a histogram
    1d 1 mm 300 1. 1.3
