Sherpa

The CIAO 4.1 release includes the a complete, non-beta version of the redesigned Sherpa, the CIAO modeling and fitting application. Sherpa is provided for interactive analysis of Chandra X-ray data; however, it is general enough to be equally useful for analysis of images, spectra and time series from many other missions (even from optical missions such as Hubble).

The redesigned Sherpa is meant to be flexible, modular and extensible. As such, Sherpa is an importable module for both the Python and S-Lang scripting languages, with user interfaces in both languages. Sherpa model, optimization and statistic functions are also available via both C++ and Python for software developers wishing to link such functions directly to their own compiled code. The CIAO 4.1 release of Sherpa also contains many improvements over the beta release of Sherpa that was part of CIAO 4.
