+	* src/main/java/de/intevation/flys/artifacts/model/WstValueTableFactory.java:
+	  Sort by rows (should not be necessary).
+
+	* src/main/java/de/intevation/flys/artifacts/model/WstValueTable.java:
+	  Use unsharp km lookup (epsilon = 0.0001). This fixes the problem
+	  that some kms were not found.
