Category PHASING_MIR_DER

Name:
'phasing_MIR_der'

Description:

   Data items in the PHASING_MIR_DER category record details
   about individual derivatives used in the phasing of the
   structure when methods involving isomorphous replacement are
   involved.

   A derivative in this context does not necessarily equate with
   a data set; for instance, the same data set could be used to
   one resolution limit as an isomorphous scatterer and to a
   different resolution (and with a different sigma cutoff) as an
   anomalous scatterer. These would be treated as two distinct
   derivatives, although both derivatives would point to the same
   data sets via _phasing_MIR_der.der_set_id and
   _phasing_MIR_der.native_set_id.

Example:
