    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 53 seconds over 30 days 11 hours 59  minutes  7  seconds;  the 
    cycle interval and time values have been corrected.
