| Abstract: |
Sherpa is the Chandra Interactive Analysis of Observations
(CIAO) modeling and fitting application. Written in Python, with efficient C,
C++, and Fortran extensions, Sherpa enables the user to construct complex models
from simple definitions and fit those models to data, using a variety of
statistics and optimization methods. Sherpa is a general-purpose fitting engine
with advanced capabilities, and has been used as a backend for the development
of new applications like Iris, the Virtual Astronomical Observatory spectral
energy distribution builder and analyzer. However, building and installing
Sherpa as a standalone Python package was problematic, and such a build would
not maintain all of the Sherpa capabilities. For version 4.7 (December 2014)
Sherpa's build scripts have been completely rewritten, standardized, and made independent of
CIAO, so that Sherpa can now be built as a fully functional standalone Python
package, and yet allow users the flexibility they need in order to build Sherpa
in customized environments. |
