    * mfilter/MFMagicCuts.[h,cc]:
      - added the usage of the new SlopeLong parameter for ghostbusting
+
+   * mjobs/MJStar.cc:
+     - preselect events for muon analysis not only by size but also
+       by fConcCOG.
+
+   * mmuon/MMuonSearchPar.[h,cc]:
+     - added a new member function to return the dist (sqrt(x^2+y^2))
+     - to create outliers which are outling as much as possible we
+       let the fit change x and y to infinity.
+
+   * mmuon/MHSingleMuon.cc:
+     - adapted the histogram binning from Siegen slices to ns.
+     - adapted the par limits for the fit to ns
+     - adapted the starting value for the rms to ns
+     - removed the fit range, it was anyhow identical to the histogram 
+     - changed the condition of the pixel index into a condition
+       of the pixel size

+     will now be in ns, too. This might also mean that the Muon
