    keyword=Data taking for multi-12C

    We took production data on Multi-foil 12C target. 1.5 millon events on left and over 2 million events on right.
    Left+BB, with a little over 1KHz rate, deadtime is <20%.
    Right+ND, with 4KHz rate, deadtime is 24%. Tried to change pre-scale factors, seems not change deadtime. Turned out that we had a wrong PS data file. Once we had the correct file, changed prescale T1=2
    for run 21058, deadtime is much smaller (a few %).
