Notes. * Used contour line 10−2 of the peak intensity; ** used contour line 10−4 of the peak intensity; the rest events used contour line 10−3 of the peak intensity.
The longitudinal separation between the magnetic footpoint of SC, assuming the solar-wind speed of 400 km/s, and flare location. Dlon: Positive values mean that the footpoint is located to the west of the flare, and negative values indicate the east side.
Low(L): ≤0.5 MeV. Medium(M): (0.5, 5) MeV. High(H): ≥5 MeV.
‘-’ in 2 and 13 means the data gap in solar wind or mag data.
“x” symbol in 7, 8, and 9 means no shock arrived at PSP afterward. The nose of 7 is within a CME.
