Draft LBT Operations Model• LBT will be scheduled in partner blocks of
7-10 nights.• Partners will send only experienced
observing teams to the LBT.• Observing teams will queue observe
partner’s programs.• Telescope reconfigurations, including AO,
are permitted. Number/night is TBD.• LBTO will provide daytime and nighttime
technical support, LTO, and IQ Specialist.

Interventions and ToO with the LBT
• No policy currently in place.
• Discussed by Science Advisory Committee (SAC) in May 2002.
• Some partners may be interested in receiving notifications and acting on them.
• Consortium-wide agreements may be difficult to achieve.
• Models from similar partnerships may be helpful in formulating a LBTO policy.
