----- IDENTIFY OPTIMAL TEMPORAL OR SPATIAL SHIFT NECESSARY -----
          TO MAXIMIZE CORRELATION BETWEEN TWO DATA SERIES

 * Number of data points in stratigraphic series 1: 1000 
 * Stratigraphic series length (space or time): 999 
 * Sampling interval (space or time): 1 

 * Number of data points in stratigraphic series 2: 301 
 * Stratigraphic series length (space or time): 300 
 * Sampling interval (space or time): 1 

 * NOTE: Using the default minpts value of 150 
         Allowable values are from 2 to 301 

 * Optimal shift identified using r-value maximum ( r= 1 ): 200  
 * Optimal shift identified using r2-value maximum ( r2= 1 ): 200
