Fig. 2


Spectral model and data for GRB 061122. The violet triangles are the 20−200 keV ISGRI data points used for the fit. The coloured dots covering the energy range 40−1000 keV are the data from the 11 SPI detectors with the highest signal-to-noise ratio selected for the spectral analysis (cf. McGlynn et al. 2009). We fitted the cut-off power-law model in this case, with α = −1.3 and E0 = 263 keV (see Sect. 5 on spectral analysis).
