+4a. Create the needed *.so libs @ ISDC
+======================================
+
+FACT data are stored in (gzipped) fits files, but the data files are too large to be read by the existing tools: 
+
+`pyfits <http://www.stsci.edu/institute/software_hardware/pyfits>` which uses `cfitsio <http://heasarc.gsfc.nasa.gov/fitsio/>`_.
+
+To mitigate this problem a C++ class defined in fits.h [#f1]_ is used. A simple possibility to create an interface of this C++ class is to use ROOT and later to import it using the
+`pyroot <http://root.cern.ch/drupal/category/package-context/pyroot>`_ module.
