PLAT066

 The predicted and reported transmission ranges are found to be identical   
 which is not to be expected. CIF's generated with SHELXL97 report  
 transmission ranges based on the crystal dimensions supplied on the
 SIZE card. Those values have nothing to do with the actual corrections 
 for absorption as applied to the data: they just report the EXPECTED range.
 Some correction packages (e.g. SADABS) will provide only one   
 'relative-correction-factor'. In such cases, Tmax should be given as   
 Tmax-expected and Tmin = relative-correction-factor * Tmax.
