Zero Slopes Status 09oct2023

  1. The Firmware Patch is being tested in the daytime
    1. Approx. 7 days total (22-Sep-2023 to 05-oct-2023).
    2. Closed loop with ARGOS source.
    3. On Oct 5th two slope zero events occurred; one on DX and one on SX.
  2. During night observing (no firmware patch), between 22-Sep and 04-Oct, there were 11 slope zero events (3 on SX, 8 on DX).
  3. Next steps for LBT
    1. Given that slope zero events have occurred in day tests with the new firmware in place, discuss whether it makes sense to deploy it for use at night.
    2. Revisit the possibility to deploy the work-around (i.e., 1 Hz overwrite of the offending DSP variable).
  4. Next steps for Arcetri SOUL team
    1. Re-plan (given that slope zero events have been reproduced in day tests with the new firmware in place).
