    keyword=Look at sieve runs

    I took Mike's holecheck.C macro and modified it so that that
    one can put cuts on Erecoil and ytgt and the 2d plot
    of sieve is done after cut on ytgt and Erecoil. No need to run the separate sievecheck.C . The macro are in the online directory.
    To switch between root files in offline (adaql10) and online
    replay one needs to change lines in the macro. Runs 1035-1037
    were replayed by Steffen again so they have the right gold variables.
    For run 1144 I did online replay of 150,000 events.

    I found that for run 1035 for full replay
    with single carbon foil and cut on one hole
    about 365 counts. ( set erecoil cut to 1000)

    For run 1036 ( multifoil) for full replay
    for the center foil with one hole 770 counts
    and for the foils at the edge of the acceptance with one hole 250 counts.

    For run 1037 10cm LH2 for full replay for tight ytgt cut of +/-0.005m and the center hole 600 counts. With no ytgt cut the center hole had 2800 counts.

    For run 1144 , Erecoil < 0.020 and ytgt between +/-.04 get
    235 counts in center hole after replaying 150,000 events.
    But the right arm dipole was not set right during runs
    1143 and 1144 so it will have to be done over.
