Out of Observing
Out of Observing at 16:32 UTC to try and tune up A2L and SQZ. We might be losing lock from earthquakes in a few minutes.
Our range hovered around 150 Mpc overnight, here's a screenshot of the darm coherence checks from the operator LowRangeChecks
This shows that some of our noise around 20 Hz is due to ASC, so we want to run A2L to see if we can improve that.
Want to change gain from 3.19 to 3.25, rounded to 2 decimal places. St.Div is 0.56. Change of -0.061
H1:SUS-ETMX_L2_DRIVEALIGN_P2L_SPOT_GAIN => 3.25
Want to change gain from 4.89 to 4.9, rounded to 2 decimal places. St.Div is 0.99. Change of -0.011
H1:SUS-ETMX_L2_DRIVEALIGN_Y2L_SPOT_GAIN => 4.9
by the time we started ETMY the earth was shaking so much that the measurement wasn't good. I've put these ETMX values into the guardian.
SQZ ZM sliders updated and accepted in sdf
ETMX spot gain values updated in the Observing snap file
