Category DIFFRN_SCALE_GROUP

Name:
'diffrn_scale_group'

Description:

   Data items in the DIFFRN_SCALE_GROUP category record details
   of the scaling factors applied to place all intensities in the
   reflection lists on a common scale.
   Scaling groups might, for example, correspond to each film in a
   multi-film data set or each crystal in a multi-crystal data set.

Example:

Example 1 - based on CAD-4 diffractometer data obtained for Yb(S-C5H4N)2(THF)4.
