S_Rate Signal sampling rate in samples/second
N_sample Number of samples of the signal
Duration Durationof the signal is secends
Nseg Number of segments of the signal (healthy signal has one segment and no gap)
Fseg Fraction of segments (if no data is missing, this fraction will be 1)
NSpk Number of spikes captured and corrected automatically
Qual Quality number (check the assocaited paper for details: Qual=1 is healthy signal and Qual=6 absolutely useless)
PGA[cm/s/s] Peak ground acceleration in cm/s/s
PGV[cm/s] Peak ground velocity in cm/s
