 Alert Level A:



CHEMW_01  Alert A The ratio of given/expected molecular weight as calculated    
          from the _chemical_formula_sum lies outside                           
          the range 0.90 <> 1.10

DENSD_01  Alert A The ratio of the submitted crystal density and that           
          calculated from the formula is outside the range 0.90 <> 1.10         
          Crystal density given    =      5.259

General Notes



ABSTM_02  When printed, the submitted absorption T values will be replaced      
          by the scaled T values. Since the ratio of scaled T's is              
          identical to the ratio of reported T values, the scaling does         
          not imply a change to the absorption corrections used in the          
          study.
