STATE of H1: Preventive Maintenance
OUTGOING OPERATOR: Corey
CURRENT ENVIRONMENT:
SEI_CONF state: WINDY
Wind: 4mph Gusts, 2mph 5min avg
Primary useism: 0.02 μm/s
Secondary useism: 0.32 μm/s
QUICK SUMMARY: 65 hour lock, but we are currently out of observing because ETMY violin modes 1000.30 & 1000.31Hz are rung up quite high. Since these are right next to each other, damping is proving to be difficult. The bandpass filters for each of them are broad, about 0.1hz, so it covers both of the modes for each filter bank. For right now I'll just try to find a phase and gain combo that may work before trying to change any filters.
I will stay out of Observing for the time being because the violins are clearly seen in the DARM BLRMS, glitch grams, and our range. If I get their log RMS values close to 5 I'll most likely go back into Observing.
