Powder dictionary (pdCIF) version 1.0.1

Category PD_PROC_LS

Definition:

   This section is used to define parameters relevant to a
   least-squares fit to a powder diffractogram, using a Rietveld
   or other full-profile (e.g. Pawley or Le Bail methods) fit.

   Note that values in this section refer to full-pattern fitting.
   Use the appropriate items for single-crystal analyses from the
   core CIF dictionary for structure refinements using diffraction
   intensities estimated from a powder diffractogram by 
   pattern-decomposition methods. Also note that many entries in 
   the core _refine_ls_ entries may also be useful (for example
   _refine_ls_shift/su_*).
