Over the last week, we've made a few tweaks to the SUS DriftMon such that it can be a quick tool to use when checking for drifting or misaligned suspensions. I've linked a smaller, more user friendly version of the monitor to the sitemap which can be tucked in a corner if useful. If channels are yellow or red and further investigation is needed, pop open the larger screen via the button in the lower right corner. From the larger screen you can also update the alarm levels to capture latest-and-greatest alignment. I have updated the monitor to a full lock time from this last weekend (2/09 14:10 UTC, 1107526216 GPS). I have adjusted the alarm thresholds of the SUS channels such that they tell you: YELLOW = you are close to the previously saved alignment, so likely just need some minor alignment tweaks RED = you are too far away from the previously saved alignment. If values are RED, and you are starting an initial alignment, it might mean: - The GUARDIAN for the SUS is in a misaligned state - WFS pointing offsets or FM integrators have been left on and need resetting - Possible temperature change in the VEA Note, RM1,2 and OM1,2,3 thresholds are pretty wide so I wouldn't expect them to go into alarm. These suspensions are not used to point beams into the IFO but instead direct beams onto WFS/PDs so we are more forgiving of their pointing. The OM chain might see more commissioning so we will tweak these alarm levels as needed.
