The Sh signal was found to lead the PSh by 20ns at the AND. We explicitly measured several of the overlaps and found the 20ns offset to be extremely consistent. This means that the T6 trigger will now be timed off the PSh and will come 20ns later then it used to. (Both the Sh and PSh signals were 150ns wide coming out of the discriminator.)
This will have the following consequences:
1. The ADC gates will come 20ns later then they used to. This should be fine, but must be confirmed with the data. 2. The TDC stops all come 20ns later then they used to. This will impact the MWDC t0 timing and will show up in any coincidence peaks. Offsets in the database will need to be added.
