Calibration Measurement September 20, 2025

At the time of starting the calibration suite, we had been locked for 8.5 hours and so were fully thermalized.

Adding a comment here to note two things:

The thermalization adjustment of the SRCL offset appears to still be performing well according to the grafana page.

There is a 2% difference in TST actuation strength between the model that was pushed on 8/23 to the model created from this measurement. This is also reflected in kappa TST being about 1.02 after thermalization. This is likely due to charging. Tagging CAL and SUS.
