The current version is science tools v9r33p0-fssc-20140520.

The Fermi Science Tools have been updated and the details are below.
We have built and tested the tools on Scientific Linux 6, (32 and 64
bit), OS X Mountain Lion.

We have also tested the tools on the Scientific Linux 5 32 and 64 bit
distributions, on Ubuntu 10.04, on Fedora 18, and 20, as well as OS X
Mavericks.  

The binary distributions without the ROOT plotting and GUI package are
also available for these systems. In these systems plotting via python
has replace ROOT plotting. 
=======================================================================
Mac OS X
In some cases the user may see an error message of the form

"dyld: Library not loaded: /opt/local/lib/libfreetype.6.dylib"

Please see the installation instructions for a remedy. 

=======================================================================
Fermi Science Tools UPDATES:

- updated gtselect to fix minor bugs. 

- Changed extension name for healpix output from "SKYMAPS" to "SKYMAP"
  for consistency with galprop/gardian/galplot tools 

Likelihood/pyLikelihood/optimizers:
- Define additional plotting symbols

- throw exception from NewMinuit::Minos if Minuit2::MnMinos does not
  find a valid lower or upper confidence limit 

- improved memory management in gtmodel. 

- improved memory management when reading the spacecraft file. 

A new tool to allow the analysis of burst data. The tool is gtburst,
and is a python GUI tying together several tools and helping to
automate burst analysis. A thread on the use of this tool is being 
developed and will appear on the FSSC website soon. 


=======================================================================
Fermi User Contributed Tools UPDATES:

The tool to generate Fermi LAT light curves using likelihood analysis 
(like_lc.pl) and aperture photometry (aperture.pl) has been updated to
accept the CALDB for the irfs. 

=======================================================================

Note: This release of the new photon data is to update a component in 
      the Galactic diffuse model so the user should be sure to use the  
      gll_iem_v05_rev1.fit model. The isotropic component is unchanged
      but the components have been renamed with an _rev1 for
      consistency with the Galactic diffuse model but the column name
      in the photon files have not changed. So to use the new files in
      your analysis the xml should contain,

    <source name="iso_source_v05" type="DiffuseSource">
    <spectrum file="<Path to File>/iso_source_v05_rev1.txt" type="FileFunction">

     to define the file and column names.
