The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value ' 1/[\s^2^(F) + 0.0003F^2^],
\s(F) from counting statistics' 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^(F) + 0.0003F^2^], \s(F) from counting
statistics'.
