We had to rerun the report to account for pro-spring in the model. Calibration looks better now -- sensing model is within 2% above 20 Hz and 5% below 20 Hz, report attached. I also updated the .ini file to now account for the pro-spring behavior.

More detailed steps:

  1. Set is_pro_spring to True at the pydarm_H1.ini in report 20250614T183642Z
  2. Rerun report 20250614T183642Z (in terminal, ran $pydarm report --regen --skip-gds 20250614T183642Z)
  3. Copied current pydarm_H1.ini file at /ligo/groups/cal/H1/ifo as pydarm_H1.ini.250610 to save previous configuration.
  4. In /ligo/groups/cal/H1/ifo/pydarm_H1.ini , set is_pro_spring to True
