ixpeobssim¶
ixpeobssim is a simulation and analysis framework specifically developed for the
Imaging X-ray Polarimetry Explorer (IXPE).
Given a source model and the response functions of the telescopes, it is designed
to produce realistic simulated observations, in the form of event lists in FITS
format, containing a strict superset of the information included in the publicly
released IXPE data products.
The core simulation capabilities are complemented by a suite of post-processing applications which support the spatial, spectral, and temporal models needed for analysis of typical polarized X-ray sources, allowing for the implementation of complex, polarization-aware analysis pipelines, and facilitating the inter-operation with the standard visualization and analysis tools traditionally in use by the X-ray community.
Important
ixpeobssim is made available and maintained on a best effort basis under
the GNU General Public License v3,
in the hope that it will be useful, but it is not officially maintained by
either NASA or ASI.
The IXPE page on the HEASARC
should be considered the ultimate source of information for everything concerning
the observatory and the analysis of the science data it provides. Should there
be any discrepancy between the information included in the ixpeobssim code
and documentation and that provided by the HEASARC, the latter should be assumed
to be correct. (And we kindly ask users to report any such instance on our
issue tracker, so that we
can fix it.)
The ixpeobssim development takes place on a
git repository hosted on on
github.
The Installation, Overview and Quick start pages should be
enough to get you up and running. If that is not the case, or should you encounter
any issue at all, we encourage you to use our
issue tracker to file for
bug reports and feature requests.
For convenience, a static version of the latest documentation in pdf format is available at this link.
