Note
titleTechnical notes
  • Fluxes are given in units of ph × cm−2 s−1 in the 0.1 ÷ 300 GeV energy band.
  • Science Tools: v9r15p2
  • Results are obtained with unbinned likelihood using iLat and FA-dedicated scripts.
  • "diffuse" fits are downloaded via the new astroserver as suggested by Tony Johnson. An example for the daily run:
    ~glast/astroserver/prod/astro --database AstroPass6p105 --eventClass "event_class > 2"
    --minTimestamp 272160002 --maxTimestamp 272246402
    --output-ft1 Filtered_evt_00419_diffuse.fits store
  • IRF used : P6_V3_DIFFUSE
