 hydrogen atoms were added to the urea molecules according to standard
 geometry and refined using a "riding" model.  The Uiso of each hydrogen
 was refined as 1.2 times the equivalent isotropic atomic displacement
 of the nitrogen atom to which it is attached.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc
w=1/[\s^2^(Fo^2^)+(0.1184P)^2^+1.4180P] where P=(Fo^2^+2Fc^2^)/3' was
changed to 'calc'. New tag '_refine_ls_weighting_details' was
