15 | * December 18, 2000 * | |
16 | * Internal view of the ITS track parametrisation as well as the order of * | |
17 | * track parameters are subject for possible changes ! * | |
18 | * Use GetExternalParameters() and GetExternalCovariance() to access ITS * | |
19 | * track information regardless of its internal representation. * | |
20 | * This formation is now fixed in the following way: * | |
21 | * external param0: local Y-coordinate of a track (cm) * | |
22 | * external param1: local Z-coordinate of a track (cm) * | |
23 | * external param2: local sine of the track momentum azimuthal angle * | |
24 | * external param3: tangent of the track momentum dip angle * | |
25 | * external param4: 1/pt (1/(GeV/c)) * | |
