I.O.S. Data Processing of Off-Shore Pressure Recorder Data  2               
1. Because the pressure is integrated over 890 seconds and then logged, the 
time  value  assigned  to  a data cycle has been chosen as the mid-point 
between the start and end of each integration period.                    
2. Instrumental drift and depth have been removed, thus a drift free series 
is produced with an artificial mean value.                               
Clock gained 40 seconds over 35 days 14 hours 14 minutes  20  seconds;  the 
cycle interval and time values have been corrected.
