Alpha

Format

N_r, N_i, alpha // float, float, float

Optical properties for shell material. $N_r$ and $N_i$ are real part and imaginary part of refraction index, respectively. $\alpha$ is the absorption coefficient.

The 1st line is the data for outer space (0th shell), the 2nd line is the data for 1st shell, the 3rd line is the data for 2nd shell, etc.
