 Alert Level C:



ABSMU_01  Alert C The ratio of given/expected absorption coefficient lies       
          outside the range 0.99 <> 1.01                                        
          Calculated value of mu =     0.142                                    
          Value of mu given      =     0.140                                    


 0 Alert Level A = Potentially serious problem
