I did for the third time the "tutorial" on GRB analysis tools using LAT data. This time I used the version of Science Tools for the Third Checkout.
I didn't find particular problems, except for the issue mentioned by Seth. In particular why the tools ask for the FT2 file while there's no need for it? The results of the analysis on the strongest burst are at this page http://www.ts.infn.it/~longof/grb_tutorial_4.html^{Image Removed}
Now I'm going to check the joint spectral analysis.

I tried to follow the joint spectral analysis tutorial on GRB using LAT and GBM data. I'm using the version of Science Tools for the Third Checkout. I found again the problem regarding the issue mentioned by Seth. In particular when I have to bin the GBM data for the joint spectral analysis I need the FT2 file. Since they are not coherent in time, this prevents any further analysis. The results of the analysis on the burst GRB07018417 will appear at this page http://www.ts.infn.it/~longof/grb_tutorial_5.html^{Image Removed}. I'll try without the FT2 file.

I tried the joint spectral analysis tutorial on GRB using LAT and GBM data. The puzzling results of the analysis on the burst GRB07018417 are on this page http://www.ts.infn.it/~longof/grb_tutorial_5.html^{Image Removed}. I have probably to check something in the data I've produced. Or probably there are different spectral components. I discovered that I took a too long period for the LAT data selection resulting in an unphysical low flux. For fitting the data with XSPEC, special care are needed for the initial values. Still the resulting spectrum is not good.

Finally I tried the temporal analysis on GRB using LAT data. I followed Johann tutorial .. the link for his work is ftp://ftp-glast.slac.stanford.edu/glast.workingGroups/ScienceTools/tutorials/slides/GRB_083105/tutorial.html^{Image Removed}
The results are on this page http://www.ts.infn.it/~longof/grb_tutorial_6.html^{Image Removed}. More documentation on gtburstfit is needed.
