Category PHASING_AVERAGING

Name:
'phasing_averaging'

Description:

   Data items in the PHASING_AVERAGING category record details
   about the phasing of the structure where methods involving
   averaging of multiple observations of the molecule in the
   asymmetric unit are involved.

Example:

Example 1 - hypothetical example. 
 
    _phasing_averaging.entry_id     'EXAMHYPO'
    _phasing_averaging.method
    ; Iterative threefold averaging alternating with phase
      extensions by 0.5 reciprocal lattice units per cycle.
    ;
    _phasing_averaging.details
    ; The position of the threefold axis was redetermined every
      five cycles.
