.. currentmodule:: sherpa.astro.xspec



This document describes the base classes for XSPEC models, and
the utility routines - such as querying and retrieving
the abundance table information. The models provided by XSPEC
are described in :doc:`astro_xspec`; also see :doc:`astro_xspec`
for a general description of the ``sherpa.astro.xspec`` module.
