                    Daily  : 119-point convolution filter (Bloomfield, 1976)    
                             centered on noon applied to the hourly data        
                             with respective periods of the 95, 50, and 5%      
                             amplitude points at 124.0, 60.2, and 40.2 hours    
                    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 and agree well with
                             Callao and La Libertad.  The timing is poor from
                             Jan 1981 - Feb 1982.
