Notes. Best-fit parameters for the absorbed broken power law. The absorption is fixed to its Galactic value, 3.17 × 1020 cm-2 (Kalberla et al. 2005). (1) Instrument and observation date. (2) Soft photon index below EB. (3) Hard photon index above EB. (4) Break energy in units of keV. (5) Fit statistics of the broken power-law model. (6) F-test p value, i.e. likelihood that the null-hypothesis model is correct (see Sect. 3.1 for details).
