problem using model_spectrum and brightest

Hi:

I'm following the example on page 23 of the manual to
identify the brightest lines in a model spectrum which
I define as:

# id    Temp         Dens         Abund        Norm   
    Vturb       redshift
#       (K)          (cm^-3)                          
    (km/s)              
1	3.14e6	     1.e-3	  1.0	    1.0		   200.0	0.0
2	79.7e6	     1.e-3	  1.0	    0.02960599     200.0    
   0.0
3	7.56e6	     1.e-3        1.0       0.003366989   
200.0        0.0
4	33.4e7	     1.e-3        1.0       0.02999968    
200.0        0.0

but when I type 

g=brightest(10,where(wl(10,12)));

I got

"all lines have flux = 0"

I'm reading just the pha2 files as in the example.

Thanks
Juan
