The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value '
calc w=1/[\s^2^(Fo^2^)+(0.0654P)^2^+0.0000P] 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^)+(0.0654P)^2^+0.0000P] where P=(Fo^2^+2Fc^2^)/3'.
