The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc w = 1/[s^2^(Fo^2^)+(
0.1000P)^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^)+( 0.1000P)^2^] where
P=(Fo^2^+2Fc^2^)/3'.
