Seismometer and BRS data are in the following .mat files:
1. GPS1115604016_5k_quiet
2. GPS1115781616_5k_Windy
3. GPS1097109956_5k_Windy2_2

The GPS time is indicated in the file name. The first data was under low-wind speeds while the other two were under high wind speeds.
The first two files contain 8 Hz data in five columns as follow:
Column 1: T240 X velocity data, calibration factor = 1 nm/s.
Column 2: raw BRS angle data, calibrated factor = 2.13 nrad.
Column 3: raw BRS ref data, calibration factor = 1 nrad.
Column 4: wind speed magnitude, calibration factor = 1 mph.
Column 5: wind speed direction, Calibration factor = 1 deg.

File no.3 has an additional column: T240 data after 3 hrs. same calibration factor as above.
