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)
