    * mbase/MProgressBar.cc:
      - fixed initial size
+
+   * mastro/MAstro.[h,cc]:
+     - changed the code for the rotation angle back to its original
+       shape. The definition I tried to introduced was already
+       correctly implemented (assuming that sin is the x-component
+       of the vector I had it wrong in my mind twice, using
+       atan2(y,x) everywhere I did recognize it...)
