US National Gemini Office

Users Support Portal

The US National Gemini Office (US NGO) main goal is to support US Gemini Users in the phases of the astronomical observing cycle, from proposal preparation to data analysis. This page is the main portal to all information for the different phases, connecting to specific Gemini pages, where users can find definitive content on instruments and modes. This page also contains data reduction and analysis tools for the entire Gemini community. In addition to the US NGO, Users can also contact the members of the Users' Committee for Gemini Observatory (UCG) for their partner country, listed on the Gemini Observatory governance page.
