CL04 is constant strain rate loading

Active seismic recordings:

/CL04_ACTIVE_SEISMIC/
bottom_sensor_active_CL04.ascii  % recordings from receiver at the bottom and source at the top / 16384 rows (individual waveform time-series with dt=2e-8s) vs. 18 columns (individual shots)
top_sensor_active_CL04.ascii     % recordings from receiver at the top and source at the bottom / 16384 rows (individual waveform time-series with dt=2e-8s) vs. 18 columns (individual shots)
times_sec_from_loading_active_CL04.ascii  % timing of individual shots as seconds from loading time (18 entries)
Note: This is raw data, recorded at 60db pre-amp gain. To convert to 'equivalent' recording at 70db (as per CL10), multiply by sqrt(10)
(because going from 60 db to 70 db involves multiplication by 10 ^ (10/20) = sqrt(10) )

Acoustic emission recordings:

/CL04_AE/
bottom_sensor_AE_CL04.ascii % recordings from bottom receiver / 16384 rows (individual waveform time-series with dt=2e-8s) vs. 2235 columns (individual AE)
top_sensor_AE_CL04.ascii    % recordings from top receiver / 16384 rows (individual waveform time-series with dt=2e-8s) vs. 2235 columns (individual AE)
times_sec_from_loading_AE_CL04.ascii % timing of individual AE as seconds from loading time (2235 entries)
Note: This is raw data, recorded at 60db pre-amp gain. To convert to 'equivalent' recording at 70db (as per CL10), multiply by sqrt(10)
(because going from 60 db to 70 db involves multiplication by 10 ^ (10/20) = sqrt(10) )

Estimated system delay through sample:
This estimate was based on an experiment whereby the pistons touched together (sample-less experiment)
2.6493e-05s to correct for pistons and for any external factor delay (recording system etc)
