_refine_special_details 
; 
 Refinement on F^2^ for ALL reflections except for 678 with negative F^2^ 
 or flagged by the user for potential systematic errors.  Weighted R-factors 
 wR and all goodnesses of fit S are based on F^2^. R-factors based 
 on F^2^ are statistically about twice as large as those based on F, and R- 
 factors based on ALL data will be even larger. 

 Note the paucity of data which leads to a low quality refinement, manifesting 
itself as large temperature factors for all atoms and the need for geometrical 
restraints on the carbons of the vinyl groups.
