  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.
