H1 SQZ
sheila.dwyer@LIGO.ORG - posted 06:49, Wednesday 19 November 2025 (88167)
sqz data set FIS, nominal psams, script left running

unamplified seed: 0.0055 amplified seed: 0.052, deamplified: 0.00073 NLG = 9.45, seems too small

no sqz: 1447564297 - 1447565492
reduced seed, adjusted temp: amplified max:0.00547 minimum 8.3e-5, unamplified: 2.54e-4 NLG 21.5

FIS, ran scan sqz angle kHz, CLF 6 demod phase left at 149.7 degrees. 1447566037

I started the script to scan squeezing angles with FIS, Ryan Short gave me a pointer on how to have my script change guardian states (puts SQZ ANGLE SERVO to IDLE now).  It is set up to try the current angle +/-10 degrees, run through a bunch of angles in 20 degree steps, flip the CLF sign and run through angles again.  When finished it should request frequency dependent squeezing again and Ryan has set things up so the IFO should go to observing when that happens.  

The script ran anf completed, the IFO didn't go to observing when it completed because I forgot to turn off the pico controler after I lowered the seed.  Here is the log of times:
