US National Gemini Office

The US NGO main goal is to support US Gemini Users in the phases of the astronomical observing cycle, from proposal preparation through data analysis. This page is the main portal to all information needed in the different phases, explaining and connecting to specific Gemini web pages, where users can find definitive contents on instruments and modes. In addition, this page contains tools for data reduction and analysis for the entire Gemini community.  All Gemini Users are encouraged to contact us with questions and comments.
