Replication Data for: Statistics of Large Impulsive Magnetic Events In The Auroral Zone

This data set contains three files, described below. DS01.txt: SMDA harmonic distortion event times (UTC). Harmonic distortion event start times for February 2014 - October 2017. The first line is a header which describes column information. Data is comma separated. DS02.txt: SMDA even harmonic distortion data from the Tilly substation transformer as used in Fig. 6. Each event has been baselined such that the minimum EHD for each event is 0. The first line is a header which describes column information. Data is comma separated. Missing harmonic distortion data corresponding to an impulsive event are marked with all 0 values. This data set is for the impulsive-event triggered EHD Data seen in panel e of Fig. 6. DS03.txt: SMDA even harmonic distortion data from the Tilly substation transformer as used in Fig. 6. Each event has been baselined such that the minimum EHD for each event is 0. The first line is a header which describes column information. Data is comma separated. This data set is for the time periods with similar SME values as seen in panel k of Fig. 6.
