At that time it was found that the optimal focus for lbti was -8.5, and with the lmircam dichroic it was -8. The primary issue is finding a location where the source is visible on both lmircam and svis (no such place was located)
  • From UT20231228, bayside position for LBTI -36.857, -43.014 showed no vignette from dichroic.
  • From UT20240129, z stage for LBTI was found to be -5.7

UT20230107 23:47 starting up the LBTI WFS and setting up for tests
  • Noise pattern on OCAM to start. Rebinning resolved
  • Set sweetspots to sharktest
  • flat set with 620 modes
Personal emergency just came up. Argos arm parked, shell rested. The teams will see if Greg can help.
