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.
