-        MTUQ distinguishes between the following different types of 
-        time shifts
-    
-        - `static_shift` is an initial user-supplied time shift applied during
-        data processing
-        
-        - `time_shift` is a subsequent cross-correlation time shift applied 
-        during misfit evaluation
-        
-        - `total_shift` is the total correction, or in other words the sum of
-        static and cross-correlation time shifts
