Data have been edited and mathematically compensated for aircraft orientation 
and magnetic effects.  Ground truth data from and observatory and from a      
localized aeromagnetic survy over the observatory are used as input to a      
computer program that mathematically solves for a set of compensation         
coefficients, which are then applied to the data.  No temporal variations     
have been removed and data below 15,000 feet are not smoothed.
