The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value ' w = 4F~o~^2^[\s^2^(F^2^) +
(0.02F~o~^2^)^2^]^-1^' was changed to 'calc'. New tag
'_refine_ls_weighting_details' was created. The value of the new tag
was set to 'w = 4F~o~^2^[\s^2^(F^2^) + (0.02F~o~^2^)^2^]^-1^'.
