After some ITMX ISI work, PRY initial alignment work and more Guardian work, variable finesse technology has been used to bring the PRMI close to the dark fringe. This time the normalization of the error signals is done with POPAIR_A. The success is only in principle because once we arrived at the final step to transition to RF for MICH, an earthquake sadly hit us..the bad timing of this earthquake is unbelievable (#%$#&*&!). 
The positive news is that with this new alignment the recycling gain is somewhat higher than before. We don't have precise measurements because we haven't really locked stably on the dark fringe yet, but we think we had a recycling gain around 10 at some point during the MICH offset reduction sequence when the alignment was good.

Jim's ITMX ISI measurements are about to start, and they will last until tomorrow around lunch time.
