1 ICLNUM I ! Drift cell number
2 DRIFT F ! Abs drift distance (cms)
3 ERRDRF F ! Error in drift distance (cms)
4 ISGNW I ! Bit 0 not used.
! Bit 1 not used.
! Bit 2 0=>O.K. 1=> dubius drift
! Bits3-6 not used.
! Bit 7 0=>O.K. 1=> bad timing
! don't use.
5 CHARGE F ! Charge integral
6 DRIFTP F ! Drift distance for +side tracks
7 DRIFTM F ! Drift distance for -side tracks
!
! NOTES:
!
! The drift distances are NOT signed.
!
! DRIFT is the drift distance to be used in conjunction with
! the EFFECTIVE stagger when it is not known which side of the
! wire plane the track went. There are then 2 possible space
! points given by:
! EFFECTIVE stagger + DRIFT
! and EFFECTIVE stagger - DRIFT
!
! DRIFTP and DRIFTM should be used when the drift sign is known:
! Geometric Stagger + DRIFTP
! or Geometric Stagger - DRIFTM
!
! >>>> Exception: If drift time comes out negative after
! subtraction of T0, then DRIFTs will be negative.
! They should however be used as described above.
!
! 1) If there was a close preceding hit or long leading edge,
! the drift resolution is degraded and Bit 2 in ISGNW set.
! 2) Bit 7 is set if the pulse had insane drift times or zero
! measured charge. Such pulses should never be used.
! 3) So:
! ISGNW =0 => Pulse was O.K. Even errors might mean
! something.
! ISGNW > 0 => Pulse was problematic but can be used.
! Errors have been inflated in ad hoc way.
! ISGNW > 127 => Don't even think about using this hit.
