    keyword=re: hana results

    Regarding the hana results. 1) The VDC multiplicity is simply the
    sum of hits on VDCs, including multiple hits on wires (raw event length).
    The holes which appear are a binning effect. Root decides the binning
    when I plot this variable from an ntuple. If you look carefully at the
    histogram you can see the holes are meaningless. 2) tch is the "TC"
    measured on H-arm TDC, while tce is the familiar TC. There are some
    notes available about that these mean and why bumps appear. Short answer
    is yes, the bump at 265 in tce is a missed retiming effect. 3) I agree
    that the E-arm VDCs are less efficient. The hana plots all ~400 wires
    in one plot. The first 1/4 is U1, next V1, etc.

    I will try to print out some commented reference plots before I leave
    and leave them in a folder.
