    keyword=re: timing of PSh discriminator in the T6 trigger

    OK, so after seeing no timing shift after adding the PSh we rechecked cabling at the Sh.AND.PSh unit and confirmed that we had confused which cable was which.

    The Shower signal is the one that comes 20ns after the PSh. That means that there is no timing shift on T6, consistent with what we observed in runs 1911, 1912.

    So no database updates are needed. And Kalyan and I need more sleep and/or more coffee... Argh.
