SQZ OPO Temp and SQZ angle adjusted to improve squeezing
TJ popped us out of observing so Vicky and I could touch up the OPO temperature 0.017degC (step3 of 70050) and adjust the SQZ angle 2degrees. The temperature change made the biggest difference in SQZ BLRMs, plot.
Knew this needed to happen as our range trended downwards with the SQZ BLRMS (sitemap> SQZ>Overview> SQZ Scopes> SQZ BLRMS), plot of 14 hour lock attached.
