Standard Analysis Environment

Specific tools, referred to as Science Tools in GLAST parlance,  have been developed  for  analyzing  the LAT data,  as made necessary by
the scarcity of photons and the broad PSF at low energy.  A general presentation is given here ( pdf , html ) and more information can be found
 here . The analysis workhorse is the Likelihood tool developed by Jim Chiang (see here  for Jim's excellent tutorial).
The instructions for installing  the Science Tools are given in the User Workbook .

On the simulation side, the package obsim allows one to model  AGN-like sources by means of the SpectralTransient class. This class  takes  into
account any input light curve and the redshift-dependent spectral cutoff due to absorption by the Extragalactic Background Light. 

High-level simulations

Results of  recent simulations  concerning  AGN studies with  GLAST will be posted here.
