The respective light travel time has been added to the solar release times in Table 2 of Kollhoff et al. (2021) and the uncertainty in the estimated SEP release times is given in minutes. In the parenthesis, we note the method used for the release time determination, (T) and (V) for TSA and VDA methods, respectively. The energy range used in each case can be found in Table 2 of Kollhoff et al. (2021).

Characteristic times when the pressure/shock wave connects to the spacecraft. ‘First’ is the first time when the pressure wave connects to the s/c, ‘Shock’ is the time when the first shock regions connect to the spacecraft, ‘Super’ is the time when the connected shock regions become supercritical. For the ‘Shock’ case the characteristic times are determined when the median values of X become greater than unity and for the ‘Super’ case when the median values of M_A become greater than the M_c = 2.0. The ± values that are given on the right are minutes from the characteristic times that have been determined at the time when the distribution max (min) values pass above the defined thresholds. For ^( † ) we determined the shock connection time from the third quartile values instead of the median. For ^( ‡ ) we used the third quartile values and M_c = 1.5.

Maximum/plateau values of M_A at the field lines magnetically connected to the spacecraft estimated from the results of Fig. 10.
