FSSC Science Tools Data Selection and Caveats Fermi
FSSC Science Tools Data Selection and Caveats Fermi Data Analysis Workshop Boston University, Jan. 11, 2010 Liz Hays 1 Event selection Use Events >100 MeV for spectral analysis To avoid spurious features due to rapidly changing effective area with energy
and because of residual uncertainty in the instrument response. Small uncertainty in energy scale results in relatively large systematic error in final result. Fermi Data Analysis Workshop Boston University, Jan. 11, 2010 Liz Hays 2 Event selection Use "Diffuse" class for diffuse, extended, and point source analysis. (evclsmin=3,
evclsmax=3). NOTE - this applies to P6 IRFs only, future recommended event selections might change. Other event classes have higher charged-particle background contamination and may result in spurious spectral features. Residual cosmic-ray (charged particle) background. Spectral templates are provided for the diffuse class event selection that allow you to account for the presence of residual cosmic-ray backgrounds in your model fits.
