            mg/cm2, at all other energies = 0.41 mg/cm2.

           Also, for neutron energies less than twice the bias    
            energy, the neutron detector efficiency error is      
            included.                                             
           Above that energy, the uncertainty in the shape of the 
            (relative) efficiency curve was assumed to be 2% per  
            10 MeV neutron energy difference and was not included.
           (DATA-ERR2) Scale error due to uncertainty in          
            reference values plus uncertainty in areal density    
            of targets.
