    Revision History:-
    ================
 
    5.00  D. Wark     First version.
          H.S. Wan    Added mnemonics and removed unused words.
          N. West     Add link to MCTK. Move __START_TIME add _THETA, _PHI.
    5.02  N. Oblath   Added double-precision pulse-time and 
                      electron-arrival-time words
                      FIRST_DRIFT_TIME actually a float (not double), 
                      and includes only the track-segment central-value time
                      Added FIRST_E_ARRIVAL_TIME, which includes time smearing
    5.03  N. Oblath   Added KMCNT_TRACK_LENGTH and KMCNT_NUM_SEGMENTS
          N. Oblath   Added KMCNT_TOT_ENERGY_DEP
          N. Oblath   Added KMCNT_MIN_SIGMA
	  H.S. Wan    Added KMCNT_ENDCAP


 
Description
-----------
 
There is one MCNT for each charged track that passes through an individual NCD counter.
 
Reference Links
---------------
 
 -4  -KMCNT_MCTK   MCTK  The MC track that produced this MCNT as it entered an NCD counter.
 -3  -KMCNT_MCNT   MCNT  The next track that contributes to the same MCNC
 -2  -KMCNT_MCNC   MCNC  The unamplified current bank this track incursion contributed to.


Structural Links
----------------
 
 -1  -KMCNT_MCNI   MCNI  The first ionisation segment of the track. 
 
 
Status Bits
-----------
 
Note: Any status bit parameters are defined to work with bit functions such as
      IAND and BTEST.

Notes
-----

1)  This word is single precision (time is usually stored in double 
    precision) because the zebra routine ZSORT is used to arrange the 
    MCNT banks in temporal order. ZSORT takes single precision arguments only.
