The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc
w=1/[\s^2^(Fo^2^)+(0.0459P)^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^)+(0.0459P)^2^]
where P=(Fo^2^+2Fc^2^)/3'.
