    5959   * mimage/MHVsSize.cc:
    6060     - changes some comments
     61
     62   * mmuon/MHSingleMuon.cc:
     63     - skip the "error estimation" step. It is just a multiplication
     64       with a fixed value. This doesn't influence enaything. And the
     65       absolute avlue of the error is not used at all.
