INTEGER
. CL(MAXTRK,2) ! True and seen history class of track :
! 0 : from Vertex
! 1 : from decay of strange particle
! 2 : from decay of D+-
! 3 : from decay of D0
! 4 : from decay of other charmed
! particle
! 5 : from decay of beauty particle
! 6 : from strange particle,
! coming from D+-
! 7 : from strange particle,
! coming from D0
! 8 : from strange particle,
! coming from other charmed
! particle
! 9 : from strange particle,
! coming from beauty
! 10 : from decay of D+- coming
! from a beauty decay
! 11 : from decay of D0 coming
! from a beauty decay
! 12 : from decay of other charmed
! particle coming
! from a beauty decay
! 13 : from strange particle,
! coming from D+-,
! which in turn comes from
! a beauty decay.
! 14 : from strange particle,
! coming from D0,
! which in turn comes from
! a beauty decay.
! 15 : from strange particle,
! coming from other charmed
! particle,
! which in turn comes from
! a beauty decay.
! 16 : from tau-decay
! 17 : electron from gamma
! conversion
! 18 : electron after brems-strahlung.
! 19 : From long-lived particle
! decay (pi+-,K+-)
! 20 : From nuclear reinteraction
! in the detector
! 22 : Unknown.
! any of the above + 30 :
! The ultimate ancestor of the
! particle was a particle
! of a kind the user requested
! to save (or set a non-zero
! life time to)
! The seen class will normally be 0 for
! all particles. However, if ZAURST is
! called (directly, or by calling ZAVF1),
! track-pairs compatible with the K0 or
! Lambda hypothesis will get seen class = 1
! NB: IN THE NEAR FUTURE CHANGES WILL BE
! DONE HERE. THE ABOVE CODES WILL REMAIN
! VALID, BUT MORE WILL BE ADDED.
INTEGER
. ANC(MAXTRK) ! Line of the parent of the track
! (0 if the particle is from the primary
! vertex, and not from a particle type that
! the user has selected to keep).
