Everything with these trends looks normal, except for the ITMy SUM. This now appears to be a failing laser diode (previous issue reported here), so the oplev laser was swapped this afternoon while LLO was down.
For the HAM2 oplev, this can likely be removed from the script as the HAM oplevs are now set for decomissioning (ECR E1700123 and ECR tracker 7884).
