The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value ' w= [\s~F^2^~ + (0.015F)^2^ +
0.5]^-1^ (Killian & Lawrence, 1969)' was changed to 'calc'. New tag
'_refine_ls_weighting_details' was created. The value of the new tag
was set to 'w= [\s~F^2^~ + (0.015F)^2^ + 0.5]^-1^ (Killian &
Lawrence, 1969)'.
