 Alert Level C:



ABSTM_02  Alert C The ratio of expected to reported Tmax/Tmin(RR) is > 1.10     
          Tmin and Tmax reported:      0.232     0.547                          
          Tmin and Tmax expected:      0.183     0.503                          
          RR =      1.167                                                       
          Please check that your absorption correction is appropriate.

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:   H11 N1 O11 P3 Zn2.5          
          Atom count from _chemical_formula_moiety:H88 N20 O4                   

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      0.919                            
          Tmax scaled      0.503 Tmin scaled      0.213
