+    * mmontecarlo/MMcTriggerRateCalc.cc:
+      - Fixed: MMCTrigHeader could not be found in the case of camera
+	files containing single trigger condition. To be fixed: selection of
+	one condition within a file with several.
+    * macros/trigrate.C
+      - no plot is made in the case of single trigger condition.
