GBM Light curves

Notes:

• 1) The data are from the Fermi-SDC: http://heasarc.gsfc.nasa.gov/FTP/fermi/data/
• 2) The light curve is generated using the Fermi-tool gtbin for the TTE data.
• 3) The individual panel shows the GBM light curve for each GBM detector (GBM-BGO: b0 and b1, GBM-NaI: from n0 to nb) in full energy range.

LAT Sky Image

Notes:

• 1) The data are from the LAT photon server: http://fermi.gsfc.nasa.gov/FTP/fermi/data/lat/allsky/
• 2) The LAT image is created using the Fermi-tool gtselect and gtbin.
• 3) The GBM position with 35 degree radius is used to create the image.
• 4) The energy range is from 100 MeV to 300 GeV.
• 5) The image is searched using ximage detect command. If ximage detect command finds any significant source, the result is shown at the bottom of the image
• 6) Green circle is the GBM error circle.

LAT light curves

Notes:

• 1) All the photons within a radius of 35 degrees from the GBM position are used to construct the light curve (because the GBM location is not that accurate).
