 Replacing the "\%beta" substring with the "\b" substring in the values
 of the _chemical_name_systematic and _chemical_name_common data items.

 Antanas Vaitkus,
 2017-03-29

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc
w=1/[\s^2^(Fo^2^)+(0.049P)^2^+0.03P] where P=(Fo^2^+2Fc^2^)/3' 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^2^)+(0.049P)^2^+0.03P] where P=(Fo^2^+2Fc^2^)/3'.
