              Present Data : Hourly, daily, and monthly values obtained by:     
                    Hourly : Nine-point triangular filter centered              
                             on the hour with respective periods of the 95, 50,

                    Daily  : 119-point convolution filter (Bloomfield, 1976)    
                             centered on noon applied to the hourly data

                    Monthly: Simple average of all daily values; calculated if  
                             7 or fewer days are missing

              Comment      : The daily and monthly means reveal no apparent     
                             changes in the reference level.  Timing accuracy   
                             was no better than plus or minus 7 minutes.  This
                             series is distinguished from Enewetok-A because
                             the data have not been linked to a common datum.
