Semester 2014A Time Distribution

 

Overview

The time available on each of Gemini North and South is distributed according to the Observatory partners' shares. To maintain overall balance amongst the partnership, the allocations are adjusted each semester as a result of actual time charged in prior semesters. The allocations are approved at the Operations Working Group meeting prior to the Call. 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 science time available at each telescope includes a 7% Director's Discretionary Time allocation and 1 night for instrument performance monitoring. The Director's Discretionary Time is divided into a maximum 5% share for use by staff (which is open for joint proposals with the partners), and a minimum 2% share available to all astronomers through the Director's Discretionary Time proposal process. The time available for each partner and host institution in 2014A is shown in the Tables below. The number of nights is approximated by int(hours/10).

 

Gemini North: Time Availability and Distribution

A minimum of 93.4% of the time will be available for science use on Gemini North in 2014A, which amounts to 169 nights and includes 3 nights of System Verification of GMOS with Altair and 3 nights for early science with GRACES. The non-science time will be used for observatory maintenance tasks, commissioning of GMOS with Altair, and commissioning of GRACES. Any unused engineering time will be returned to science.

Gemini South: Time Availability and Distribution

A minimum of 83% of the time will be available for science use on Gemini South in 2014A, which amounts to 151 nights and includes 4 nights of guaranteed time for the GSAOI instrument team, 1.5 nights for GMOS-S CCD upgrade demonstration science, and 7 nights for GPI early science. The non-science time will be used for observatory maintenance tasks, to complete GPI commissioning, commission the GMOS-S Hamamatsu CCDs, and commission GSAOI on a side port. Any unused engineering time will be returned to science.
