/*****************************************************************************
 *  Use GetExternalParameters() and GetExternalCovariance() to access the    *
 *      track information regardless of its internal representation.         *
 * This formation is now fixed in the following way:                         *
 *      external param0:   local Y-coordinate of a track (cm)                *
 *      external param1:   local Z-coordinate of a track (cm)                *
 *      external param2:   local sine of the track momentum azimuthal angle  *
 *      external param3:   tangent of the track momentum dip angle           *
 *      external param4:   1/pt (1/(GeV/c))                                  *
 *                                                                           *
 * The Get*Label() getters return the label of the associated MC particle.   *
 * The absolute value of this label is the index of the particle within the  *
 * MC stack. If the label is negative, this track was assigned a certain     *
 * number of clusters that did not in fact belong to this track.             *
