Semester 2011B Time Distribution
You are here
Gemini North: Time Availability and Distribution
A minimum of 88% of the time will be
available for science use on Gemini North in 2011B. This amounts to 162 nights and includes 1.5 nights for
GMOS-N CCD
demonstration science.
The remaining time will be used for observatory maintenance tasks and commissioning of GMOS with the new CCDs. 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 2011B is given in the following table.
Partner | Estimated Hours Available |
US | 613 |
UK | 278 |

Gemini South: Time Availability and Distribution
A minimum of 78% of the time will be
available for science use on Gemini South in 2011B. This amounts to 144 nights,
and includes 90 hours of NICI
campaign science, which are distributed across the
partners that participate in the campaign.
The remaining time will be used for observatory maintenance tasks, and
Flamingos-2 and GSAOI commissioning activities.
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.

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 2010B. The time allocations also include a purchase by Brazil of 35 hours of UK time at each telescope. The values shown in the tables above were recommended by the Operations Working Group in February 2011. The number of nights is approximated by int(hours/10).
