To remove high frequency noise, a low pass filter has
been applied to all the flight line data above 15,000
feet.  Data at the  beginning and end of a flight are
noisy because the aircraft is maneuvering during it's
climb or descent to or from survey altitude which is
approximately 25,000 feet.  Data below 15,000 feet or
climb and descent data are not smoothed.
