Gemini Web Information Overview

This page is out of date and will be going away soon: The USNGO web pages have moved here: - please update your links and bookmarks.

General information:  Information about how to handle your Gemini data can be found at  This page includes Gemini web page links that discuss all the data processing steps from quallity assessment through publication and observer feedback.  Some of the most useful links are:

Getting your data:  All data must be retrived from the Gemini Science Archive.  If you do not already have an account there are instructions for registering at the archive web site. 

IRAF: Most Gemini data reduction tools use IRAF, see the IRAF and Gemini IRAF Overview.  The latest versions of Gemini IRAF and the Ureka support packages are linked to the Gemini Announcements page.

Getting started with IRAF:  The classic starting point is the 1993 Beginner's Guide to Using IRAF by J. Barnes 1993.  A terse but more up-to-date step-by-step IRAF guide has been prepared by N. Caon at the IAC.

Other IRAF Guides:  A compilation of guides can be found on the IAC web site.  If you want to understand/write scripts you will need to consult the CL User's Guide and the Introductory User's Guide to IRAF Scripts.  Despite the names neither guide is for beginners.

Gemini IRAF (and other data reduction software) announcements, releases, contents, and news.  A quick introduction by K. Labrie was given at the 2010 NOAO Gemini Data Reduction Workshop.   Click here for instructions on loading the Ureka package (which contains Gemini IRAF) and on setting up IRAF and PyRAF.

Links by Instrument:  The Gemini web site provides links on data reduction for each instrument.  General information on near-IR observations includes wavelength calibration information, line lists, photometric, spectroscopic, telluric standard lists, spectral templates, etc. There is additional data reduction information for each Gemini instrument on the instrument's web page under the topic “data format and reduction”.

Workshops, examples, data reduction forum:  Links to Partner data workshops and the Data Reduction User Forum
