 Alert Level C:



ABSTM_02  Alert C The ratio of expected to reported Tmax/Tmin(RR) is > 1.10     
          Tmin and Tmax reported:      0.088     0.133                          
          Tmin and Tmax expected:      0.070     0.133                          
          RR =      1.255                                                       
          Please check that your absorption correction is appropriate.          

SHFSU_01  Alert C The absolute value of parameter shift to su ratio > 0.05      
          Absolute value of the parameter shift to su ratio given   0.058       
          Additional refinement cycles may be required.                         


 0 Alert Level A = Potentially serious problem

 0 Alert Level B = Potential problem
