Documentation =============== See the Users Guide and API documentation hosted at http://pythonhosted.org/pyfits. Important notice regarding the future of PyFITS =============================================== All of the functionality of PyFITS is now available in `Astropy <http://www.astropy.org>`_ as the `astropy.io.fits <http://docs.astropy.org/en/stable/io/fits/index.html>`_ package, which is now publicly available. Although we will continue to release PyFITS separately in the short term, including any critical bug fixes, we will eventually stop releasing new versions of PyFITS as a stand-alone product. The exact timing of when we will discontinue new PyFITS releases is not yet settled, but users should not expect PyFITS releases to extend much past early 2014. Users of PyFITS should plan to make suitable changes to support the transition to Astropy on such a timescale. For the vast majority of users this transition is mainly a matter of changing the import statements in their code--all APIs are otherwise identical to PyFITS. STScI will continue to provide support for questions related to PyFITS and to the new ``astropy.io.fits package`` in Astropy. Development ============= PyFITS is now on GitHub at: https://github.com/spacetelescope/PyFITS To report an issue in PyFITS, please create an account on GitHub and submit the issue there, or send an e-mail to email@example.com. Before submitting an issue please search the existing issues for similar problems. Before asking for help, please check the PyFITS FAQ for answers to your questions: http://pythonhosted.org/pyfits/appendix/faq.html The latest source code can be checked out from git with:: git clone https://github.com/spacetelescope/PyFITS.git An SVN mirror is still maintained as well:: svn checkout https://aeon.stsci.edu/ssb/svn/pyfits/trunk For Packagers =============== As of version 3.2.0 PyFITS supports use of the standard CFITSIO library for compression support. A minimal copy of CFITSIO is included in the PyFITS source under cextern/cfitsio. Packagers wishing to link with an existing system CFITSIO remove this directory and modify the setup.cfg as instructed by the comments in that file. CFITSIO support has been tested for versions 3.08 through 3.30. The earliers known fully working version is 3.09. Version 3.08 mostly works except for a bug in CFITSIO itself when decompressing some images with BITPIX=-64. Earlier versions *may* work but YMMV. Please send in any results of experimentation with other CFITSIO versions.
