+	* src/main/java/de/intevation/flys/artifacts/services/FixingsKMChartService.java:
+	  Draw domain markers for borders of Q sectors. There is some kind of glitch
+	  in in the Q sector classifaction code or the db data is strange.
+
+	  Because of the common code basis this affects the fixings calculations, too. :-(
