The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value '
calc w = 1/[\s^2^(Fo^2^)+(0.0753P)^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^)+(0.0753P)^2^] where P=(Fo^2^+2Fc^2^)/3'.
