Subject: measurement of sensing matrix : just began 

- status update on LSC activity :

The measurement of the LSC sensing matrix has begun. But no useful results yet.


 The measurement script (#4850) ran pretty well after I did some modifications to adopt the script to the latest LSC model.

However the SNR weren't so great particularly in REFL33 in the PRMI configuration.

So I will tune the amplitude of excitations and integration times tomorrow.

Currently the excitation is at 238.1 Hz, where no disturbing structures are found in the spectra.
