Possible Task (depending on performance of telescope)

  • Collect data for Tracking quality
  • Collect data for Guiding quality
  • Collect data for Active Optics quality
  • Check for pointing jump due to offloading of M2 (low priority)
    • Guide and Active Optics on medium elevation star
    • After 5 or 10 minutes, OffsetTelescope
    • Repeat OffsetTelescope every 5 to 10 minutes
    • => plot guide corrections as a function of time
      • If pointing jump due to M2 offload, then will see a large correction on the first guide image after the offset
      • Perform with Active Optics in "Default" mode (will see spikes) and in "M1" mode (should not see spikes)
      • Baseline will be to perform several OffsetTelescopes in a short time in "Default" mode (should not see spikes)
