IRAFX (despite the name) represents the recent development versions of STScI STSDAS, a software package for reducing and analyzing astronomical data and routines specifically designed for HST data, and stsci_python, our Python-based software including tools such as pyfits, pyraf, and multidrizzle. Improvements to HST pipelines and STSDAS tasks are always made first in IRAFX, before being released later to the community as part of STScI's standard IRAF release (roughly twice a year). Users who rely on such improvements and who wish to have access to the latest versions of all the software, may want to consider using IRAFX.
IRAFX is the software that the Science Software Branch is developing. Users who want to use IRAFX should be aware that, even if the software is presumed to be fairly reliable, it has not been fully tested. It may occasionally malfunction.
Users should also be aware that there is no support for this version of the software; however, we would like to hear about any problems with IRAFX. Please, report any issue to email@example.com.
The new version of IRAFX appears on our website each Monday, though we occasionally skip a week. Check the time stamp next to the download link.
Documentation for irafx is available on our download server.
There is a mailing list where we occasionally make announcements about IRAFX. You may also use this mailing list to discuss the features under development. Use this form to subscribe:
