The following automatic conversions were performed:
'_refine_ls_weighting_scheme' value 'calc
w=1/[\s^2^(Fo^2^)+(0.0535P)^2^+8.1837P] where P=(Fo^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^(Fo^2^)+(0.0535P)^2^+8.1837P] where P=(Fo^2^+2Fc^2^)/3'.
