19// Class AliPositionObj
20// Handling of positions in various reference frames.
21//
22// This class is meant to provide an AliPosition object which is derived
23// from TObject such that it can be stored in e.g. TObjArray etc...
24// and that it can be written out using the ROOT I/O machinery.
25//
26// Example :
27// =========
28//
29// Float_t a[3]={1,2,3};
30// Float_t ea[3]={0.01,0.02,0.03};
31// Float_t b[3]={4,5,6};
32// Float_t eb[3]={0.04,0.05,0.06};
33//
34// AliPosition r1,r2;
35//
36// r1.SetPosition(a,"car");
37// r1.SetPositionErrors(ea,"car");
38// r2.SetPosition(b,"car");
39// r2.SetPositionErrors(eb,"car");
40//
41// Ali3Vector sum=r1+r2;
42// Ali3Vector rel=r1-r2;
43//
44// AliPositionObj rr1(r1);
45// AliPositionObj rr2;
46// rr2.Load(r2);
47// AliPositionObj ssum(r1+r2);
48//
84bb7c66 49// rr1.Data();
50// rr2.Data();
51// ssum.Data();
