SSB IRAF + Python Software Distributions
Ureka has been deprecated as of 04/26/2016. Please consider switching to STScI's Conda-based solution, AstroConda. Current and previous versions of Ureka will remain available for download and installation, but will no longer receive updates.
The Science Software Branch (SSB) distributes three software bundles that contain many useful astronomy packages, including:
- IRAF 2.16
- Python 2.7
- STScI Python (including PyRAF)
There are three different distributions because of ranging user needs: some want the bleeding-edge development software (SSBDEV and SSBX), while others need a more stable environment (SSBREL).
Using SSBREL, SSBX, or SSBDEV
- If you are on the internal network, see these instructions for users at STScI.
- If you are an outside user, you'll need to install these builds yourself. Follow these instructions for external users.
As of 04/26/2016:
No futher updates will be applied to SSBREL.
This is the final public release.
A full list of included package versions can be found here.
As of 04/26/2016:
The SSBX distribution is no longer functional due to recent changes in our build infrastructure. Please use SSBDEV instead.
This package contains everything in SSBREL, except that it has current versions of SSB development software (including JWST pipeline, STScI Python, CRDS, and HSTCAL packages)
A full list of included package versions can be found here. Documentation for STScI Python in SSBX can be found here.
We update SSBX on Sundays between 9 PM and 3 AM.
As of 06/22/2016:
The SSBDEV distribution is no longer rebuilt nightly. The final build will remain available.
We update SSBDEV every night between 9 PM and 3 AM.
PyRAF is a Python replacement for the IRAF CL. There is a description at http://www.stsci.edu/resources/software_hardware/pyraf, including a tutorial.
We are no longer developing PyRAF and we only have the resources to provide minimal support for it.
You can find some information about configuring PyRAF here.
You can find some outdated notes for Mac users here. Topics include how to install CDBS from a DMG file and how to remove obsolete files in /usr/stsci.
If you have any questions or problems, please send mail to firstname.lastname@example.org. Be sure to include "SSBREL", "SSBX", or "SSBDEV" (as appropriate) in the subject line.
