DIRC activities

Paged around suppertime August 8th about the water in the tank on the DQM checklist being around 1 cm too high. Assured the pilot that we were aware of this and altered the short term instructions to reflect this knowledge.

I would have been paged August 11th about high bin 11 (data truncation) by the swing DQM shifter, but it was me. Basically this was due to the high luminosity (11+). MCC was able to tune it down somewhat, getting it just under .1%, and since the data quality was unaffected (looking at the fast monitoring) Emmanuele said we could live with it. Watching the DIRC background over the next few days however, MCC managed to keep it way down while running at >11*1033.
