Notes. We adopted the time windows from previous analyses performed by Ackermann et al. (2014) and Cheung et al. (2016b), which differ from the 15 day time window used for the results presented in Appendix A. The energy cutoff for V5668 Sgr is not constrained by the fit. We therefore present the results of a simple power-law fit without a cutof,f for which we find that the TS value decreases only insignificantly from 89.0 to 87.5.
