The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc w=1/[s^2^(Fo^2^)+(
0.0693P)^2^+2.0895P] 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^)+( 0.0693P)^2^+2.0895P] where
P=(Fo^2^+2Fc^2^)/3'.
