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).
