checkCIF procedure

PLAT964

 Two weight parameter values reported in the CIF weight expression string
 '_refine_ls_weighting_details' are found to differ from those archived in the
 WGHT parameter value list in the embedded ',res' file. The latter values are
 assumed to be the correct ones as part of the final refinement. 
 Recreation of the FCF from the embedded '.ins' & '.hkl' files will result in
 inconsistent wR2 and S values and associated ALERTS in the checkCIF report
 when those weight parameter values differ. Please also check the proper
 format of the SHELXL weight expression string.
