+
+! EXPLANATION OF WINDOW PARAMETERS
+
+!To select the desired branch of the cross-correlogram, we employ a Tukey window. A Tukey taper is just a variant of a cosine taper. We use three control parameters
+
+!W_DELAY controls the time offset of the window
+!W_WIDTH controls the width of the window (i.e., the total time range over which the window has non-zero support)
+!W_TUKEY controls the sharpness of the drop-off
+
+!In noise tomography applications, W_DELAY should be roughly equal to the surface wave travel time from the one receiver to the other.
+
+!Checks on W_WIDTH are carried out to make sure that the window makes sense and lies within a single branch of the cross-correlogram. If the the window falls outside these bounds, it will be adjusted.
+
+!W_TUKEY is a number between 0 and 1, 0 being pure boxcar and 1 being pure cosine
