US National Gemini Office

Welcome to the US NGO Users Support Portal!

The US National Gemini Office (US NGO) is a group within the Community Science and Data Center (CSDC) at the NSF NOIRLab. Our main goal is to support US Gemini Users in the phases of the astronomical observing cycle, from proposal preparation to data analysis. Information about the US NGO members can be found at our people page.

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, 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.

If you have any questions, comments, and/or feedback, send us an email at usngo@noirlab.edu or a direct message on Twitter or BlueSky.

If your question is more elaborate and involves Gemini data reduction, we encourage you to submit a Gemini Helpdesk Request.

Data Reduction Tutorials

GitLab Repositories

Our tutorials are based on the examples provided by the Gemini/DRAGONS team. The links below will take you to the repositories with examples and extended help files:

DRAGONS: Jupyter notebooks (using the DRAGONS Python API)
IRAF: Gemini/IRAF scripts
XDGNIRS: The GNIRS XD reduction pipeline

Astro Data Lab

Astro Data Lab also hosts several jupyter notebooks that can guide you on how to reduce your Gemini data. Launch a Notebook, get the latest notebooks and you will find them on 04_HowTos/DataReduction/.
