The following automatic conversions were performed:

data item '_refine_ls_weighting_scheme' value 'calc
w=1/[\s^2^(Fo^2^)+(0.0513P)^2^+294.0152P] 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^)+(0.0513P)^2^+294.0152P] where P=(Fo^2^+2Fc^2^)/3'.
