_refine_ls_weighting_details

Name:
'_refine_ls_weighting_details'

Definition:

   A description of special aspects of the weighting scheme used
   in the least-squares refinement. Used to describe the weighting
   when the value of _refine_ls_weighting_scheme is specified
   as 'calc'.

Example:

;                  Sigdel model of Konnert-Hendrickson:
                   Sigdel = Afsig +  Bfsig*(sin(\q)/\l - 1/6)
                   Afsig = 22.0, Bfsig = 150.0 at the beginning of refinement.
                   Afsig = 16.0, Bfsig =  60.0 at the end of refinement.
