    keyword=Run 1333 - FPP WG on U1

    Found that in Run 1333 the number of hits per WG on U1 was very high, but the problem was completely gone in Run 1334, although we had done nothing in-between. Also note that in Run 1333 the TDC widths seem noisy for this WG at all times, while this was not the case in Run 1334.

    So, the cause of this problem appears to be intermittent.
