I'm happy to announce a new deployment option for Sherpa. The latest version of Sherpa, 4.2.2, built as a Mac disk image for OSX 10.5 Leopard using native (meaning Non-CIAO) python.org 2.6 and NumPy installations. This experimental build is an effort to minimize the difficulties in building Sherpa's dependencies. This build includes XSPEC 12.6.0 models (why it's so large), CIAO region file support (including FITS), CIAO dynamic grouping, and WCS support using WCSSUBS. The user is still responsible for optional packages such as DS9, XPA, matplotlib, and pyFITS. The goal of this project is to utilize the Mac simple GUI installer and install Sherpa as easily as the SciPy and NumPy disk images.
We are currently working on a Snow Leopard/universal version with upgrades to Python 2.7 and NumPy 1.5.0.
