 Alert Level A:



DIFF_019  Alert A _diffrn_standards_number is missing                           
          Number of standards used in measurement.

          _diffrn_standards_interval_time are missing. Number of measurements   
          between standards or time (min) between standards.

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      0.891
