I ran the script that Hugo prepared for me at around 7:34:30 in UTC or 0:34:30 in PDT. I confirmed that it successfully switched the blend filter for Z in ETMX ISI to the one he wanted to test. I am leaving it in this configuration as requested by Hugo.

Those who perform X arm comissioning tomorrow should not forget to switch it back to the nominal configuration by running:

/ligo/svncommon/SeiSVN/seismic/BSC-ISI/H1/Common/Misc/Test_Configuration_Scripts/Switch_To_Comm.py

Note:

before running the script, I steered ETMX to an angle which is far enough from the aligned value so that it does not interfer with the corner locking but still gives an OK centering for oplev. This resulted in  (PIT bias, YAW bias) = (403, 86).
