    keyword=setting ps4=1 for run 4422.

    My shift partner was concerned that T4 causes "negative deadtime".
    I decided this is not a real problem and we should set ps4=1 to
    measure the trigger efficiency. It should be analyzable offline.
    So with run 4422 we se ps4=1. (BTW, deadtime didn't go negative).

    Note:

    grep -ai ps2 /adaql2/data1/e07006_4421.dat.0
    ps1=35,ps2=1,ps3=1,ps4=0,ps5=1,ps6=0,ps7=0,ps8=400

    grep -ai ps2 /adaql2/data2/e07006_4422.dat.0
    ps1=35,ps2=1,ps3=1,ps4=1,ps5=1,ps6=0,ps7=0,ps8=400
