+    radar-coordinate water body is created three times in runRdr2Geo.py, runLook.py and 
+    runIonUwrap.py, respectively. radar-coordinate water body is used in:
     (1) determining the number of offsets in slc offset estimation, and radar/dem offset 
         estimation
     (2) masking filtered interferogram or unwrapped interferogram
     (3) determining the number of offsets in slc residual offset estimation after geometric 
         offset computation in coregistering slcs in dense offset.
     (4) masking dense offset field
+    (5) mask coherence in ionosphere fitting and filtering
