After Ibrahim relocked the IFO, the range is lower around 150 Mpc. Ibrahim ran the coherence checks from the low range wiki, and saw that there was braod SRCL coherence. He double checked that the SRC ASC offsets 78415 from yesterday are correctly still in place. The squeezing level is quite good in this lock.
I accidentally started to run the A2L script (by clicking in a terminal I didn't mean to), so we took a few minutes to try to retune SRCL FF. We tried the feedforward that Gabriele fit last week, 78307, which gives us worse coupling than the April 29th filters do. Then we adjusted the gain using the April 29th filter, screenshot attached. The SRCL coherence is still highly, and the range is still low. We would need a new filter to get good SRCL decoupling in this lock, but we do not understand why this has changed since last lock.
