15 * Use GetExternalParameters() and GetExternalCovariance() to access the *
16 * track information regardless of its internal representation. *
17 * This formation is now fixed in the following way: *
18 * external param0: local Y-coordinate of a track (cm) *
19 * external param1: local Z-coordinate of a track (cm) *
20 * external param2: local sine of the track momentum azimuthal angle *
21 * external param3: tangent of the track momentum dip angle *
22 * external param4: 1/pt (1/(GeV/c)) *
