Above Left: From top to bottom, >10 MeV, >100 MeV, >30 MeV, >50 MeV, >60 MeV fluxes showing threshold (red dashed line), threshold crossings (black dotted lines), estimated onset peak (black circle), and maximum flux (red open circle). Plot will be missing if no threshold was crossed. Note that onset peak algorithm is sometimes tricked (>30 MeV). Above Right: All integral fluxes with start and end times for the different energy channels (dashed lines). Left: Fluence spectrum for integral fluxes calculated by applying the start and stop times derived for each channel. |
