Movie S1

Movie s1
The movie shows the portion a 60 degree portion of the sky centered on the reconstructed location of GRB080916C, starting from 200 seconds before the GBM trigger and ending 400 seconds after the trigger. The integration time of each frame is 100 seconds, and each frame is shifted by 5 seconds with respect to the previous one (100 frames in total). The dark blue dots represent the events with reconstructed energies below 100 MeV, the green dots are the events with reconstructed energies between 100 MeV and 1 GeV, and the red dots have energies above 1GeV. A Gaussian smoothing has been applied to each event to represent the point spread function of the LAT instrument. The width of the point spread function decreases with increasing energy. Where the point spread functions of several photons of different energies overlap other colors than dark blue, green and red appear. The dark portion on the lower left corner of each frame is due to the decrease in detection efficiency as a function of the incident angle (i.e. the edge of the field of view of the LAT is showing).
