 Alert Level B:



ABSMU_01  Alert B The ratio of given/expected absorption coefficient lies       
          outside the range 0.95 <> 1.05                                        
          Calculated value of mu =     0.084                                    
          Value of mu given      =     0.080                                    

THETM_01  Alert B The value of sine(theta_max)/wavelength is less than 0.575    
          Calculated sin(theta_max)/wavelength =    0.5565                      


 0 Alert Level A = Potentially serious problem

 2 Alert Level B = Potential problem

 0 Alert Level C = Please check
