With Enzo, Hatoya-san, and Hirata-san.

Today:

• Enzo and Hatoya-san had originally planned to experiment with different damper gaps by raising and lowering the top keystone, but found a curious coupling from keystone height to OL yaw.
• Rather than spend time resetting the OL, they decided to adjust the damper gap by raising the magnet ring.
• Hirata-san craned off the lid of the tank so they could access the top filter.
• They made a record of the current receptacle heights (see paper log book or photo thereof in SR3 Installation album of Google Photos) and then raised them 1 mm to give a wider gap.
• We left the tank lid off over night and set IP yaw TFs going.
