                          EPED      Run Header bank
                          =========================
 
  NB: This bank corresponds to the SHaRC EPEDRecord but is substancially
      reorganised by the Recorder in WRITE_EPED_HEADER.

    Revision History:-
    ================
 
    3.01  D. Wark     First version.
    3.02  N. West     Correct CALIBRATION_TYPE values.  
                      Add comment about _CRATE_ID and _CALIBRATION_TYPE 
                      Add comment about SHaRC EPEDRecord.
                      Add Run Number + 5 spares.

Notes
-----

 
1)  Data is recorded by half crate.  Bit 7 (=128) is set if the top half (higher
    card numbers) is being recorded. The value is incorrectly set for _BEG_END
    types greater that 2.
