14/*****************************************************************************
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)) *
