20// Class to handle systematic errors for charm hadrons
21//
22// Usage:
5541b811 23// AliHFSystEff syst; // DECAY = 1 for D0, 2, for D+, 3 for D*
24// syst.SetRunNumber(YEAR); // YEAR = two last numbers of the year (is 10 for 2010)
25// syst.SetCollisionType(TYPE); // TYPE = 0 is pp, 1 is PbPb
26// syst.SetCentrality(CENT); // CENT is centrality, 0100 for MB, 020 (4080) for 0-20 (40-80) CC...
27// syst.Init(DECAY); // DECAY = 1 for D0, 2, for D+, 3 for D*
0233abe6 28// syst.DrawErrors(); // to see a plot of the error contributions
29// syst.GetTotalSystErr(pt); // to get the total err at pt
