Semester 2010A Time Distribution

Gemini North: Time Availability and Distribution

A minimum of 80% of the time will be available for science use on Gemini North in 2010A. This amounts to 145 nights and includes 1.5 nights for a delayed Compensatory Time program. The remaining time will be used for observatory maintenance tasks, and the planned commissioning of GNIRS and the new CCDs for GMOS-N; any unused engineering time will be returned to science. Note that historically around 5% of each semester's science time is used to complete highly ranked programs from the previous two semesters to which the ITAC granted rollover status. The number of hours allocated to each partner in 2010A is given in the following table.

Gemini South: Time Availability and Distribution

A minimum of 80% of the time will be available for science use on Gemini South in 2010A. This amounts to 145 nights, and includes 18 nights of NICI campaign science, and 8 nights for Flamingos-2 Science Verification (SV). The Flamingos-2 SV is contingent on the progress of the instrument commissioning. The remaining time will be used for observatory maintenance tasks, and Flamingos-2 and MCAO commissioning activities. Any unused engineering or SV time will be returned to science. Note that historically around 5% of each semester's science time is used to complete highly ranked programs from the previous two semesters to which the ITAC granted rollover status. The number of hours allocated to each partner in 2010A is given in the following table.

Time Adjustments

To maintain overall balance amongst the partnership, the values shown above for both Gemini North and South have been adjusted from the nominal partner shares as a result of actual time charged through 2009A. The time allocations shown here were recommended by the Operations Working Group in July 2009. The number of nights is approximated by int(hours/10).
