The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc w = 1/[\s^2^(Fo^2^) +
(0.01P)^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^) + (0.01P)^2^] where P = (Fo^2^ +
2Fc^2^)/3'.
