This morning I have been looking over the trends of the OSEMs for the QUADs, for the past 1 month. I see few (2-3 at least) glitches (if at all they are) and they seems to be coinciding with lock loss trends (H1:GRD-ISC_LOCK_STATE_N). In the coming days I will give it a closer look (and discuss with Jeff.K/Sheila) and post more details (as well as trends for the ITM and other suspensions).
