We thought it's worth to get some most recent ITMY data to compare along side with ITMX to make sure there's no obvious shmud on the ITMY surface. Given the wrong in vac lens and the possibility that the alignment might have changed we might not get anything useful. But if the alignment is good in theory we should still be able to see if there's anything wrong on ITMY surface by subtracting the final gradients after power-up/lockloss from the reference (taken while resonates at 2W).
Because the two cameras can't be run at the same time, I swapped the fiber so that h1hwsmsr machine is now talking to the HWSY camera rather than HWSX camera. Data written to /data/H1/HWS_ITMX starting from 20:19:29 UTC is data from ITMY surface.
Log:
20:08 UTC HWS code stopped
20:15 UTC cable swapped
20:19 UTC HWS code restarted, now writing data from HWSY camera
The HWSY SLED has been turned on also.
