Columns 1–5 correspond to fields in the NGA-West2 flatfile, columns 6 and 7 give the PI index according to (a) Baker (2007) and (b) proposed methodology, and columns 8 and 7 give the classification of records as pulse-like, non-pulse-like, or ambiguous, according to (a) Baker (2007) and (b) proposed methodology.

* PI > 0.85 = pulse-like, PI < 0.15 = non-pulse-like, 0.15 < PI < 0.85 = ambiguous.

† PI > 0.65 = pulse-like, PI < 0.55 = non-pulse-like, 0.55 < PI < 0.65 = ambiguous.

‡ Y = pulse-like, N = non-pulse-like, A = ambiguous.
