General Notes



FORMU_01  There is a discrepancy between the atom counts in the                 
          _chemical_formula_sum and _chemical_formula_moiety. This is           
          usually due to the moiety formula being in the wrong format.          
          Atom count from _chemical_formula_sum:   C6 H25 As3 N2 O19 V2         
          Atom count from _chemical_formula_moiety:C12 H50 As6 N4 O38 V4        

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.                                                                
          Ratio of Tmax expected/reported      0.530                            
          Tmax scaled      0.119 Tmin scaled      0.093
