    keyword=Compton: Run 20189 (coincidence with electron singles)

    There was a run which was accidentally left with electron prescale!=0 last night (run 20189). The coincidences didn't work (_very_ low rates, see the clock vs numpolar in attachment 1), but the electron event clock is quite bizarre (see attachement 2).
