Additional Documentation: 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.
