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.                                                                
          Ratio of Tmax expected/reported      0.834                            
          Tmax scaled      0.834 Tmin scaled      0.629
