Today, while the cavity was locked, and the ISI was in "level 3 isolation" I took a spectra of ETMY M0 L1 and L2 stages in Long and Pitch. 

I plotted the spectra against previous ones with the suspension damped and the chamber under vacuum for the three of them. The comparison shows different configuration of the ISI

1) in blue, ISI damped in may

2) in green ISI isolated in may

3) in red ISI isolated today
