Rotation Measurement

17:22
  • SX side first
  • 226.8 starts tiger striping.
  • 225.0 starts tiger striping
  • 225.9 seems to be the best angle
  • There is a large, intermittent vibration.
  • Last luvi image 50
  • default focus is fine

19:07
  • measure bin2 rotation
  • Nominal 258.9
  • Max 260.4
  • Min 258.1
19:52
  • found light -2.99 -2.93 0.5 -250 -199
  • An emergency has come up on the telescope, we are probably finished.
21:31
  • Crisis averted.
  • Testing focus on LUCI
  • Best focus found at 55.5
22:12
  • Testing rotation, though probably superfluous.
  • Bin 1, nominal angle +1.9 causes striping.
  • Nominal angle - 0.4 causes striping.
  • Bin 2 nominal -1.5 causes striping
  • nominal +3 causes striping
  • It looks like both are probably fine.
