The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc w =
1/[\s^2^(F~o~^2^)+(0.0265P)^2^+9.9155P] where P = (F~o~^2^+2Fc^2^)/3'
was changed to 'calc'. New tag '_refine_ls_weighting_details' was
created. The value of the new tag was set to 'w =
1/[\s^2^(F~o~^2^)+(0.0265P)^2^+9.9155P] where P =
(F~o~^2^+2Fc^2^)/3'.
