The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc w =
1/[\s^2^(Fo^2^)+(0.0610P)^2^+0.9105P] where P = (Fo^2^+2Fc^2^)/3' was
changed to 'calc'. A new data item '_refine_ls_weighting_details' was
created with the value set to 'w =
1/[\s^2^(Fo^2^)+(0.0610P)^2^+0.9105P] where P = (Fo^2^+2Fc^2^)/3'.
