NOIRLab IRAF
New for 2024: NOIRLab IRAF v2.18
Introduction
The Image Reduction and Analysis Facility (IRAF) is a general-purpose software system for the reduction and analysis of scientific data. Its development started in 1984 at the National Optical Astronomy Observatories (NOAO) in Tucson, Arizona. As of January 2024, the Community Science and Data Center (CSDC) and the US National Gemini Office (US NGO) at NSF NOIRLab launched the new NOIRLab IRAF v2.18. The main goal of this modernization project was to provide a stable, fast, reliable, and accessible data reduction option to Gemini users while new and modern software is being developed for all facility instruments and modes. The limited scope of the project includes:
- Fix all OS, platform, and licensing issues in existing code.
- Port the GEMINI data reduction package and its dependencies to 64-bit.
- Update IRAF core system and external packages with needed OS and platform fixes.
User Support
For general inquiries, feedback, and installation issues, please use one of the
email addresses listed below. Bugs within the code can also be reported
through GitLab issues. Specific questions about data reduction using
the GEMINI package should be submitted to the Gemini External
Helpdesk.

Throughout the years, IRAF has also been tirelessly kept alive by a number of volunteers in the
astronomy community (including iraf.net and
IRAF Community Distribution),
providing user support, data reduction tutorials and cookbooks, and maintaining the code.
Those efforts have been appreciated.
