This morning, Travis, Jason and I knocked in the pitch alignment of the main and reaction ETMy chains (look for Jason's alog). As usual, we had to iteratively adjust the lower stage suspended OSEMs/flags. Note, the UL and UR L2 stage OSEM flags are slightly off-center in the side-shift direction due to differential roll between the chains (which has been there since the inception of this QUAD, including during the last 1-arm test). They are giving good open-light values though.
After staring at the main chain L, P, Y TFs, we (Travis, Arnaud, and I) convinced ourselves that the suspension is healthy, although there is excess noise likely due to purge air which is dropping coherence in the measurements in a few places. We've handed off to SEI such that Jim can troubleshoot a few things on the ISI for a few hours. We anticipate reattempting the full matlab suite of SUS TFs later this evening.
