Notes.

^(a)

Subtracted from the onset time in the event's highest energy channel detected in situ by the travel time along a nominal 1.2 AU path length.

^(b)

Event 7 shows large uncertainties of β^MUL, caused by the very limited number of energy channels that are dominated by power-law population.

^(c)

For event 10, the primary or PS population is fitted to a UDPL with the spectral index β₁ (β₂) at energies below (above) a break energy E_pl in both the MUL and ADD fittings.
