- Analysis
- The imaginary part 'k' of the optical constants are derived from the absorption coefficient 'alpha' of Quirico and Schmitt 1997a in the limit of small k values (k < 1e-2), i.e., with k = alpha/(4*pi*nu). k is set to zero outside bands. The real part 'n' values is constant and equal to the visible value (n = 1.24)]
