The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc w =
1/[\s^2^(Fo^2^)+(0.049P)^2^] 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^)+(0.049P)^2^] where
P=(Fo^2^+2Fc^2^)/3'.
