Grand total is 634405 elements using 5075240 bytes
Averages: number of stacks in each record
Bike_Count: number of magnet clicks
Hpos: calculated array giving horizontal displacement (m) for the profile
Pressure: digitized pressure record relative to first measurement in bits. Needs to be multiplied by -0.1078 meters/bit
Xinc: Volts/bit for converting values (not normally useful)
Yinc: Seconds/sample - used for calculating associated time array and for calculating filter parameters.
data: matrix of the records. Each column is a complete waveform. In this case there are 494 records of 1000 samples length.
dday: decimal day of year (time) each record was acquired.
time: calculated travel time array for plotting and calculating purposes.
