                    EGS4    EGS4 bank.  One for each Event
                    ======================================
 
    Contact:  S. D. Biller, Oxford.
 
    Revision History:-
    ================
 
    1.03  N. West     Converted to mixed format.
    2.06  M. D. Lay   Add total range variable.
          N. West     Remove reference link KEV_MCVX (never implimented).
    2_09  Mike Lay    Addition of materials tracking. 
    3_02  S. Biller   Space allocated to EDep increased to 30 media
    4.02  M. Neubauer Add cerenkov photon counters
    5.00  N. West     Fix format: KEGS4_NCE_* are F not I.

 
Description
-----------
 
    Records various bits of information returned from EGS4 (see below). Note
that this information is integrated over all calls to VXEGS4 in one Monte Carlo
event. The energy deposition is stored as a function of the physical media type
(1 is light water, 2 is heavy water etc). See the PEGS file for more details. 
This means that you can get all the energy deposited in the acrylic vessel, 
but the amount depositied in any one Acrylic Vessel panel is not stored.

Reference Links
---------------
 
    None.
 
Structural Links
----------------
 
    None.
 
Status Bits
-----------
 
Note: Any status bit parameters are defined to work with bit functions such as
      IAND and BTEST.
