The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc w=1/[s^2^(Fo^2^)+(
0.0436P)^2^+25.8561P] 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^)+( 0.0436P)^2^+25.8561P]
where P=(Fo^2^+2Fc^2^)/3'.
