3// AliFast TrackMaker class. //
4// //
5// //
6//////////////////////////////////////////////////////////////////////////
7// ---------------------------------------------------------------------//
8// //
9// origin: "res.f" fortran by Karel Safarik which was used to //
10// calculate the track resolution for TP. //
11// Different detectors and material can be selected. //
12// The basic routines compute information and error matrices //
13// used for the calculation of momentum resolution. //
14// see references: ASK KAREL?? //
15// //
16// C++ in AliFast framework: Elzbieta Richter-Was and Yiota Foka //
17// following general structure od Makers in //
18// ATLFast by R. Brun. //
19// //
20// purpose: provide a Maker which by using general basic routines of //
21// "res.f" computes the necessary elements of covariance matrix//
22// for the calculation of Track Resolution. //
23// Those elements are the product of the TrackResolMaker and //
24// are hold in TrackResol class. They are expected to be used //
25// together with additional information for the calculation of //
26// the smeared momenta. //
27// Additional information necessary for this calculation //
28// will be provided via classes or functions specific to the //
29// specific study and/or detectors. //
30// One can select the detector and/or material for a specific //
31// study. //
32// //
33// starting point: res.f will be initialy partially contained in //
34// AliFTrackResolMaker and in AliFDet //
35// It will be reorganised further in the framework of //
36// AliFast according to the needs. //
37// Names of variables are kept as in fortran code. //
