  // ////////////////////////////////////////////////////////////////////
  // // PURPOSE:
  // //
  // // This header file defines a reasonable style for (black-and-white) 
  // // "publication quality" ROOT plots. The default settings contain 
  // // many features that are either not desirable for printing on white 
  // // paper or impair the general readibility of plots.
  // //
  // // USAGE:
  //
  // Simply include the line
  //   #include "LHCbStyle.h"
  // at the beginning of your root program (and make sure LHCbStyle.h is 
  // in a location accessible to the compiler). Then add the line
  //   lhcbStyle(); 
  // somewhere at the beginning of your main().
  //
  // SOME COMMENTS:
  //
  // Statistics and fit boxes:
  //
  // "Decorative" items around the histogram are kept to a minimum.
  // In particular there is no box with statistics or fit information.
  // You can easily change this either by editing your private copy
  // of this style file or by calls to "gStyle" in your macro.
  // For example, 
  //   gStyle->SetOptFit(1011);
  // will add some fit information.
  //
  // Font:
  // 
  // The font is chosen to be 62, i.e.helvetica-bold-r-normal with
  // precision 2. Font is of course a matter of taste, but most people
  // will probably agree that Helvetica bold gives close to optimal
  // readibility in presentations. It appears to be the ROOT default, 
  // and since there are still some features in ROOT that simply won't 
  // respond to any font requests, it is the wise choice to avoid 
  // ugly font mixtures on the same plot... The precision of the font (2)
  // is chosen in order to have a rotatable and scalable font. Be sure
  // to use true-type fonts! I.e.
  // Unix.*.Root.UseTTFonts: true  in your .rootrc file. 
  //
  // "Landscape histograms":
  //
  // The style here is designed for more or less quadratic plots.
  // For very long histograms, adjustements are needed. For instance, 
  // for a canvas with 1x5 histograms:
  //  TCanvas* c1 = new TCanvas("c1", "L0 muons", 600, 800);
  //  c1->Divide(1,5);
  // adaptions like the following will be needed:
  //  gStyle->SetTickLength(0.05,"x");
  //  gStyle->SetTickLength(0.01,"y");
  //  gStyle->SetLabelSize(0.15,"x");
  //  gStyle->SetLabelSize(0.1,"y");
  //  gStyle->SetStatW(0.15);
  //  gStyle->SetStatH(0.5);
