Columns 1 through 7 correspond to fields in the NGA-West2 flatfile and are simply repeated here to aid in interpreting the results.

* Tp is the period of the extracted pulse in the direction of the strongest observed pulse.

† PGV is the peak ground velocity of the original ground motion in the direction of the strongest observed pulse.

‡ Orientation (° w.r.t. North) is the orientation of the strongest observed pulse, in degrees clockwise from north. For cases in which the as-recorded orientation is not available, this field takes value −999.

§ Orientation (° w.r.t. Fault Parallel) is the smallest angle in degrees between the local fault parallel orientation and the orientation of the strongest observed pulse. For cases where the as-recorded orientation or fault orientation is not available, this field takes value −999.

‖ Fault Normal Pulse indicates whether the ground motion in the fault normal direction is classified as pulse-like. This field takes a value of 1 if the fault-normal motion is pulse-like, 0 if it is not pulse-like, and −999 if the as-recorded orientation or fault orientation is not available (and thus the fault-normal direction could not be determined).

# Directivity Effect indicates if the authors believe the pulse was caused due to directivity effect (1) or due to some other cause (0). For comments explaining some classifications, see the summary pages.
