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^|Fo| +
(0.015|Fo|)^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^|Fo| + (0.015|Fo|)^2^]'.
