STATE of H1: Observing at 51Mpc
INCOMING OPERATOR: Ed
SHIFT SUMMARY: VIOLINS
LOG:
Spent all day working on the 505.805 violin mode of ETMX (mode 4). Would damp with settings from the wiki to some level a little too high to make DC readout. After trying all dofs, phases and gains for this mode, eventually pushing on pitch and yaw (setting the ETMX mode 4 L2 darm damp pitch and yaw elements to 1) I was able to get this mode down enough to get NLN. Weird. Gain was mostly limited by how rung up the 505.7 modes on ETMX got, not DAC range. It is still running this way, and these settings aren't automated. Not sure if we will want to automate this, doesn't seem right.
