As maintenance was closing out, but the Vac team was still working, I wanted to try some SEI -> PRCL measurements for a potential redo of Ryan and I's 2010 feedforward.  But, since the gate valves were closed, I changed the lscparams gaveValves flag (on ~line 99) to True, indicating that a gate valve was closed.  I forgot to change it back, and that seems to have caused the several hours of grief that TJ, Corey, and Keita worked on troubleshooting.  A big symptom of this grief was that PRMI would lock, but DRMI just never would.  Once I realized / remembered after being on the phone with the control room for a while, Corey and I changed it back to it's usual value of False, and DRMI immediately caught lock. 

As part of troubleshooting, I had Corey do a very careful initial alignment (even though he had already done one, and thought the DRMI flashes looked fine).

It seems like the acquisition sequence is going forward nicely now.  Sorry :/
