ORIGINAL
Original data (SAC files) obtained from various sources.

DECIM5
These data have been decimated 5 times to approximate
a 20 Hz sampling rate.

SIGNALS
Interesting signals, clipped but with original sampling rate.
   Nyquist rate about 55 Hz.
Interesting signals, clipped and decimated 5 times.
   Nyquist rate about 11 Hz.

LP2HZDEC5
Eveyrthing lowpassed with
   lp butter co 2 n 2 p 2
and decimated without further filtering with
   decinate 5 filter off

EVENTS
Events detected by the STA/LTA detection algorithm done by
stalta_lp.m on 2Hz lowpassed signals. The 10Hz signal is
saved in this directory, for analysis with events.m and
further spectral characterization.
