=== ATLAS ===

ATLAS is using 'isasugra.x' from the isajet package to calculate SUSY mass spectra.
mSUGRA benchmark points are called [[https://twiki.cern.ch/twiki/bin/view/AtlasProtected/SusyEventFilesInfo#Benchmark_points|SUx]]. 
GMSB ones [[https://twiki.cern.ch/twiki/bin/viewauth/AtlasProtected/SusyCscNote8#GMSB_Signal_sample|gmsbx]]. 

 * the script 'analyseSpectrum.py' from GridProduction package can be used to plot a mass spectrum
 * the script 'generateSpectrum.py' from GridProduction package can be used to generate mass spectrum files for a GMSB scan
