ctatools information
====================
Version: 01-00-00 (January 31, 2011)
Author: Juergen Knodlseder (knodlseder@cesr.fr)
GammaLib dependency: 00-04-05
License information
===================

What's new in this release?
===========================
See the files "NEWS" and "ChangeLog".
What are the ctatools anyway?
=============================
ctatools are ftools-like executable for the scientific analysis of
CTA observations. They are based on GammaLib, a vesatile toolbox
for the high-level analysis of astronomical gamma-ray data.
The following tools are so far available:
ctobssim - simulation of CTA observations
ctselect - event selection
ctbin - event binning
ctlike - maximum likelihood model fitting
Web sites
=========
http://gammalib.sourceforge.net - for GammaLib documentation
https://sourceforge.net/projects/gammalib/ - for GammaLib downloads
Prerequisites
=============
ctatools require GammaLib. Please refer to http://gammalib.sourceforge.net
for instructions about how to install GammaLib. The GammaLib code can
be downloaded from https://sourceforge.net/projects/gammalib/.
Once GammaLib is properly installed, make sure that the environment
variables are set correctly:
export PYTHONPATH=/usr/local/gamma/lib/python2.5/site-packages:$PYTHONPATH export LD_LIBRARY_PATH=/usr/local/gamma/lib:$LD_LIBRARY_PATH export PKG_CONFIG_PATH=/usr/local/gamma/lib/pkgconfig:$PKG_CONFIG_PATH
This is needed as GammaLib is installed by default in /usr/local/gamma and
not in /usr/local (this may be reconsidered eventually).
Unix Installation
=================
To build and install ctatools, simply type the following:
% ./configure
% make
% make install
By default ctatools installs itself in /usr/local/gamma. If you need to
install ctatools in a different location or in your home directory, use
the --prefix option to ./configure. For example:
% ./configure --prefix=/home/yourname/projects
% make
% make install
The file INSTALL details more about using configure. Also try
% ./configure --help.
Macintosh OS X Installation
============================
ctatools are known to work on various flavors of OS X. Follow the Unix
installation instructions above.
Solaris Installation
====================
ctatools compile on Solairs, but there is an issue with using it as a
shared library (see "Known problems" below).

Known problems
==============
Solaris
Although ctatools compile on Solaris using the Sun compiler, there are
problems with global symbols in the shared GammaLib library that prevent
the model registry to work correctly. Furthermore, GammaLib is not able
to catch its own exceptions, which prevents the FITS interface to work
correctly. If GammaLib is linked statically
