    keyword=Chamber 1, problem?

    Weird data for BigBite for cosmic run # 2655.
    Two plots below show hit wire distribution for the chamber 1.

    In the first plot I ploted "BB.mwdc.[plane].hit.wire" without index.
    In the second plot I did the same, however I added additional index to the variable in order to look on the first hit, so "BB.mwdc.[plane].hit.wire[0]".
    In the second case I see number of "noisy" channels. ALL these channels correspond to the ROC 10 slot 1.
    If I look on the next hits I don't see this "noise". However my statistics for the next hits is very low.

    Chamber 2 is behaving normaly as I will expect from cosmic.
