This is NOT the place to get STScI's full Python data analysis software package (MultiDrizzle, PyDrizzle, SAAclean, etc., including PyRAF). For that, go to the stsci_python download page instead.
This page is for those that want to download PYRAF ONLY.
The current version of PyRAF is v2.1 (May 2013).
This version of PyRAF can also be obtained bundled with the May 2013 version of stsci_python (v2.14).
PyRAF currently supports Python 2.6, 2.7, and 3.3 ! The Python 3 version is available as a separate download - see below.
PyRAF is also now available for Microsoft Windows! It will in general be very limited since IRAF is not available on that platform, but some subcomponents such as Astrodrizzle are available for Windows.
The current version of STSDAS is listed here.
The Latest Official PyRAF Release:
Here are the latest nightly tar-ball versions from the repository:
- v2.2.dev for Python 2.x (contains all supported features), and
- v2.2.dev-py3 for Python 3.x (beta - see FAQ 1.8).
If you plan to installing these packages from source, or if you wish to try "pip"-installing PyRAF, you may find these stand-alone-installation instructions helpful.
Windows users may use the "bsdtar" (command-line) or "7-Zip" (GUI) utilities to unpack any PyRAF downloads, or they may simply use these zipped versions of the nightly tarball: v2.2.dev-win, and v2.2.dev-py3-win.
PyRAF depends on the following other software packages which can be downloaded separately:
- Python (2.6+)
- Numpy (1.6+)
- Tcl/Tk (8.4+)
- ipython (0.12+, optional)
- matplotlib (1.1+, optional)
- pip (1.3.1+, optional)
