After a preliminary investigation by Clement, the data looked good, so we decided to try and get more data with a longer scan time. 

We tried yesterday, however, it was too windy and we couldn't keep ALS engaged in reallocation mode. Locking on IR was not a problem. 

This morning, the wind seems less, so I opportunistically re-ran the script with longer parameters to get better data. Starting at 2025-05-13, 07:41:40, I re-ran the script with:

  - offset = 0.7

  - vFSR=2.0

  - timescan=120

These parameters were determined emperically, I think it is about 1.5 FSR. The script is running now, I'll update this post when complete. 

At scan 5, we recieved notice that staff would be entering the North and West end buildings to carry out essential work. I left the scan running, around scan 8, the IFO lost lock and couldn't relock - even on IR.
