The following automatic conversions were performed:

'_exptl_absorpt_correction_type' tag value 'spherical' was replaced
with 'sphere' value.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'w = 1/[\s^2^(F~o~) +
0.000295(F~o~^2^)]' 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~o~) + 0.000295(F~o~^2^)]'.
