32<pre>
33//_____________________________________________________________
34// AliHLTTPCTransform
35//
36// Transformation class for ALICE TPC.
37//
38// Class which contains all detector specific parameters for the TPC,
39// and different useful functions for coordinate transforms.
40//
41// The class is completely static, which means that no object needs
42// to be instantiated. Function calls should then be done like, e.g.:
43//
44// Double_t eta = AliHLTTPCTransform::GetEta(xyz);
45//
46// IMPORTANT: If used as is, default detector parameters will be used,
47// and you really have to make sure that these correspond to
48// the AliROOT version you are currently working on!!
49// You should therefore always initialize the parameters by
50//
51// AliHLTTPCTransform::Init(path);
52//
53// where path is a char*, giving the path to where file containing
54// the detector parameter is located. This file should be called
55// "l3transform.config", and can be created with the function MakeInitFile.
56//
57// You can also force reading the parameters from a AliTPCParam object
58// by setting the flag;
59//
60// AliHLTTPCTransform::Init(path,kTRUE);
61//
62// where path is a char*
63// either providing the rootfile name containing the geometry or
64// the path to the rootfile which should then be called alirunfile.root.
65// Note that for both of these cases you have to
66// compile with USEPACKAGE=ALIROOT set (see level3code/Makefile.conf).
67//
68// Currently, there are 4 versions of the Transformer:
69// fVersion==kValiroot: ALIROOT-head compatible
70// fVersion==kVcosmics: Cosmics data run (2003) compatible
71// fVersion==kVdefault: means no config file has been loaded
72// fVersion==kVdeprecated: dont use old (before July 2003) style of transformer
73//
