International Time Allocation Committee

The International Time Allocation Committee consists of representatives from the national time allocation committees, as well as the Observatory itself. The ITAC is chaired by a Gemini senior-level scientist. The recommendations of the ITAC are advisory to the Gemini Director. The ITAC meets twice a year to consider joint and conflicting proposals identified in the merging process, and to recommend the programs for execution in queue and classical modes.
