DRIFT.DAT is an ascii file which contains a lagrangian corrected shiptrack.


It has the folowing columns:
1: Year
2: Month
3: Day            All times in GMT
4: Hour
5: Minute
6: Second 
7: Eastward position of shiptrack
8: Northward position of shiptrack
   (A plot with column 7 on the x-axis and column 8 on the
   y-axis gives the ship track over the period of the experiment)
9: Eastward drift calculated from the velocity in the top-bin of the ADCP
10: Northward drift calculated from the velocity in the top-bin of the ADCP
   (A plot with column 9 on the x-axis and column 10 on the
   y-axis gives the drift inferred from the ADCP data)
11: Corrected ship-track (Eastward component)
12: Corrected ship track (Northward component)
   (Column 11 = Column 7 - Column 9 &
    Column 12 = Column 8 - Column 10)

All the data is expressed in kilometers relative to the beginning of
the first release, which was taken to be at 09-Feb-1999 08:54 (GMT)
DRIFT.MAT contains the same data in a Matlab format.
A plot of these data is given in DRIFT.PS
