    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.
