Research output: Contribution to specialist publicationArticle (Specialist Publication)


IRAF is a powerful and comprehensive environment for reducing and analyzing optical astronomical data. The system was developed by the IRAF group at National Optical Astronomy Observatory (NOAO) in Tucson, Arizona, who also maintain it (including the production of versions for new types of computer) and answer queries from users. It has its own file format, programming language, command language and on-line help documentation. The package can be installed on a number of platforms: Solaris (Beta-test version), SunOS, Ultrix and VMS are supported by the IRAF group, and there is a version for Alpha machines under OSF/1 which is maintained by the Space Telescope Science Institute (STScI). This Starlink User Note is intended as a brief introduction and a pointer to IRAF's own documentation. A walk through a short IRAF session is included as an example.
