Notes.

^(a)

Also studied by Pick et al. (2006) and Wang et al. (2011, 2016).

^(b)

Solar release time of SEEs in the event's highest energy channel, the same as T_rel in Table A.1.

^(c)

Data from the SOHO/LASCO CME catalog (https://cdaw.gsfc.nasa.gov/CME_list/). K represents the CME kinetic energy, and a superscript star marks the values that are not reliable due to large uncertainties.

^(d)

No available data.

^(e)

Data from SDO/AIA at 171 Å. T represents the start time of jets at the Sun, estimated by subtracting 500 seconds from the onset time detected at 1 au. Event 9 and 10 are associated with two jets.

^(f)

Data from the GOES flare list (ftp://ftp.swpc.noaa.gov/pub/warehouse/), confirmed with GOES 1-8 Å observations. T_start is the start time of the flare at the Sun. Duration = end time - start time.

^(g)

Data from RHESSI. T_peak is the peak time of the flare at the Sun.

^(h)

HXR flares without (reliable) peak measurements.

⁽ⁱ⁾

Influenced by South Atlantic Anomaly during the considered time inverval.

^(j)

Data from the Solar Geophysical Data (ftp://ftp.ngdc.noaa.gov/STP/SOLAR_DATA/) and Wind/WAVES observations at <14 MHz. r is the derived heliocentric distance.

^(k)

Likely underestimated because the

⁴

He is dominated by a previous large solar energetic particle event (Hart et al. 2024).

^(l)

An upper-limit estimate.
