      - Added member fMirrorFraction to keep the active fraction of the
        mirror dish set in the camera simulation. Added Getter & Setter.
+       Added some comments. Update class version to 4.
+
+   * mmc/MMcRunHeader.[hxx,cxx]
+     - Removed member fTelesTheta, fTelesPhi. They make no sense since
+       telescope orientation can change from event to event in MC too.
+       Added getter and setter for fShowerThetaMin and fShowerThetaMax.
+
+   * mmontecarlo/MMcCollectionAreaCalc.[h,cc]
+     - Changed consistency check on MMcRunHeader.fTelesTheta to check
+       on fShowerThetaMin and fShowerThetaMax
+
+   * mfileio/MReadMarsFile.cc
+     - Removed obsolete check of old MC files, which needed the removed
+       data member MMcRunHeader.fTelesTheta.
