I want to calculate the polarization of two spheres.

One sphere has 1.33+0.01i refractive index and another sphere has 1.9+0.45i.

So I set ddscat.par such as :

2 = NCOMP = number of dielectric materials
'../diel/m1.33_0.01'
'../diel/m1.90_0.45'

Then, m1.33+0.01i is number 1 and m1.90++0.45i is nuber 2. Is it right?

And I set BAM file such as :

x y z a IC1 IC2 IC3 theta_DF phi_DF beta_DF
0.000000 0.000000 0.000000 0.500000 1 1 1 0.00000 0.00000 0.00000
0.000000 1.000000 0.000000 0.500000 2 2 2 0.00000 0.00000 0.00000

Because a sphere at (0,0,0) has m=1.33+0.01i which is number 1, so I set IC1=IC2=IC3=1.
And also at a sphere at (0,1,0) , I set IC1=IC2=IC3=2 because m=1.90++0.45i is nuber 2.

Is it right?
I can't sure that means of number of IC1, IC2, IC3.
