A meeting was held this week dedicated to the current issues experienced on the HWS measurements automation. As part of the meeting Giulio has prepared the following presentation

Main meeting notes were:

• It is confirmed that current statistics show that  running manually the hwsAna.py lead to successful end of the measurement sessions
• Because of larger latency of the python postprocessing, the TCS team plan for the moment to keep using the matlab postprocessing for the faster thermal transition measurement to be done by hand and the python postprocessing for the slower transients to be measured during the nights
• Automated measurements tend to fail at the very end of the sequence

Identified action items in rough priority/sequential order were:
1 - Try an automated night measurement, with smaller number of acquisitions to asses if they can end successfully (Alessio, Ilaria)
2 - redirect the output to a log file while calling hwsAna.py  inside PyHWS.py (Franco, Diego), redirect the output to a log file while calling take inside hwsAna.py (Giulio)
3 - Increase the size (possibly doubling) of the image storing area (/data/tcs) since the filling of it for the long sessions could be suspected (Franco, EGO IT)
4 - check the user setting for virgorun and standard users (since manual run are done as standard users and automated ones as virgorun) (Franco)
5 - run PyHWS as Ilaria or another standard user (Franco, Diego, Ilaria)
6 - try the use of simpletake in place of take inside PyHSAna.py
7 - make the merging of PyHWS.py and PyHSAna.py in order to eliminate a redirection level (Giulio, Rhys)
8 - Installation of latest version of the vendor main library
9 - Proceed with the python3 porting of all still python2 applications including the University of Adelaide postprocessing code (Giulio, Rhys)

So far, out of those actions:

•     Action 2.1 (redirect the output to a log file while calling hwsAna.py) has been implemented
•     Action 3 (increase size from 4 TB to 8TB) has been performed
•     Action 5 (PyHWS running as fcarbogn) has been done

This evening, after checking at the end of the shift that no other standard HWS measurements could be performed, a test measurement has been started triggering it as:

• cm_send('PyHWS','RUN', "-r INJ /virgoDev/Sa/TCS/cfg/test/INJ.cfg"
• cm_send('PyHWS','RUN', "-l INJ /virgoDev/Sa/TCS/cfg/test/INJ.cfg"

Images acquisition and processing is currently ongoing with the logs made available into: /virgoLog/TCS/PyHWSSystem.log

Tomorrow morning the outcome of the test will be checked.
