 Description
-    Reports the height of the interface above a set of locations. For each
-    location, it writes the vertical distance of the interface above both the
-    location and the lowest boundary. It also writes the point on the interface
-    from which these heights are computed. It uses an integral approach, so if
-    there are multiple interfaces above or below a location then this method
-    will generate average values.
+    Writes the height of an interface above a set of locations; for each
+    location, it writes the vertical distance of the interface above both
+    the location and the lowest boundary.
