The total intensity, navigation and altitude data were edited using interactiv
e graphics.  The GPS data, when available, were merged with ESG position data 
based on synchronized times and positions for the aircraft.  Temporal         
variations were removed from the total intensity data.  The baseline values   
for each of the three flights were 34018.5, 33979.0 and 34017.9 (nT)          
respectively.
