:mod:`Deproject` is a `CIAO`_ `Sherpa`_ extension package to facilitate deprojection of two-dimensional circular annular X-ray spectra to recover the three-dimensional source properties. For typical thermal models this would include the radial temperature and density profiles. This basic method has been used extensively for X-ray cluster analysis and is the basis for the `XSPEC`_ model `projct`_. The :mod:`deproject` module brings this functionality to Sherpa as a Python module that is straightforward to use and understand.
The module can also be used with the standalone Sherpa release, but as it requires support for `XSPEC`_ models - for the thermal plasma emission codes - the documentation will focus on using Sherpa with a `CIAO`_ environment.
