I don't know why, but TRY has somehow gotten a 0.3 count offset in the last hour. 

Rana and I are witnesses for each other that neither of us has gone into the IFO room in the last several hours (and we're the only ones here).  For some reason though, the TRY PD now has a 0.3 count offset.  We have been doing some ALS locks, but we have not run the offset script in the last several hours.  Closing the green shutter doesn't change things, and we still see the offset when the MC loses lock, so it's not to do with the end or the PSL laser.  We haven't been in there, so there hasn't been a change in the room lights.
