The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc
w=1/[\s^2^(Fo^2^)+(0.0745P)^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^)+(0.0745P)^2^+0.0000P] where P=(Fo^2^+2Fc^2^)/3''.
