Since the yaw ASC cross couplings to DARM were high in our last lock, Ibrahim and I took a couple minutes before going into observing to run the script that TJ edited yesterday (78419) again. The attached screenshot shows that in our first time running the script the ADS values were still drifting when the script moved on to measuring the next step. This might have been because the IFO had locked recently, or because it needs to wait longer. We added a 30 second wait after we change the A2L gains before checking the values by adding +30 on line 185, after this it looked like things had settled well.
We ran the script for all test masses yaw only from the terminal using: python a2l_min_multi.py --quads ETMX ETMY ITMX ITMY --dofs Y
After the script ran, there were many SDF diff that Ibrahim has screenshots of. It would be good to edit the end of the script to have fewer of these diffs each time we run it. We added these new values to lscparams and loaded ISC_LOCK.
Here are our first and second run results.
