////////////////////////////////////////////////////////////////////
// PURPOSE:
//
// This macro defines a standard style for (black-and-white) 
// "publication quality" LHCb ROOT plots. 
//
// USAGE:
//
// Include the lines
//   gROOT->ProcessLine(".L lhcbstyle.C");
//   lhcbStyle();
// at the beginning of your root macro.
//
// Example usage is given in myPlot.C
//
// COMMENTS:
//
// Font:
// 
// The font is chosen to be 132, this is Times New Roman (like the text of
//  your document) with precision 2.
//
// "Landscape histograms":
//
// The style here is designed for more or less square plots.
// For longer histograms, or canvas with many pads, 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);
//
