Notes. The associated shock parameters are from https://stereo-ssc.nascom.nasa.gov/pub/ins_data/impact/level3/STEREO_Level3_Shock.pdf.

(1)

The first (second) number in each bracket indicates how many shocks were observed within two days before (after) the corresponding shock indicated in the column (2).

(2)

Transit speed of the associated CME.

(3)

Magnetic compression ratio of the shock.

(4)

The electron energy channel shows the strongest signal in terms of normalized data.

(5)

The Δt shows the time between the peak intensity and the shock-crossing in minutes. Negative numbers refer to peaks in the upstream region and positive numbers indicate peaks in the downstream region of the shock.

(6)

Best averaging time window for each event. ( * )SIR shock occurs one day before the shock-crossing time.
