Summary
The analysis script used for the integrating sphere (IS) calibration has been updated to the latest version. Previously, during the Pcal-X calibration conducted on May 29, the script had not been updated in the calibration environment, and as a result, clicking the ANALYSIS button on the MEDM screen (CAL_S_PCAL_CALIBRATION.adl) resulted in an error. This required manually running the script to complete the analysis.
What I did
- Replaced the
IS_calibration_analysis.pyscript located in:/users/CAL/current/scripts/MeasPcalCalibration
- The new version of the script is based on:
GitLab/cal-onsite-analysis-002/o4/common/2024-11-22_IS_calibration_summary/master_python/IS_calibration_analysis.py
- This updated version includes the calculation and update of
K1:CAL-PCAL_EX_2_INJ_V_GAIN, a parameter used to equalize the injected sine wave amplitudes from path 1 and path 2 at the ETM. This feature had already been applied in calibrations since 13th May 2025(klog33762).
Outcome
After this update, clicking the ANALYSIS button on the MEDM screen will once again automatically run the updated script and perform the analysis as intended.
Additional Comments
The main purpose of this update is to restore the functionality of the ANALYSIS button on the MEDM screen. With this update, the automatic calculation and update of K1:CAL-PCAL_EX_2_INJ_V_GAIN, which has already been applied since the May 13 calibration, is now included in the script executed via the MEDM interface. Note that this functionality had already been implemented in the analysis scripts manually used during past calibrations, so this update does not affect the results of previous analyses.
