    keyword=MWDC hit drop highly depends on events range replayed

    It's showed in previous Halog that for run 3146, in the first 16k event, MWDC hit drops and there is a hot spot in shower down-right block.

    However this problem will disappear if looking at event #16k to #32k for same run. So I would guess it's more likely to be related to beam trip rather than long term problems like gas supply.

    1st Figure : Chamber hit drop for run #3126 event 1-16k
    2nd Figure : Same plot for run #3126 event 16-32k
