Detailed Description

A MeanListDustMix object represents a basic dust mix defined by optical properties fully specified inside the configuration file (i.e. without referring to an input file), describing a single representative grain and using the Henyey-Greenstein scattering mode. It is intended for use in cases where the properties are tabulated for just a few wavelengths (or even a single wavelength), but nothing keeps the user from specifying a long list.

The numbers in the four user-configurable lists specify respectively the wavelength \(\lambda\), the extinction mass coefficient \(\kappa^\text{ext}_\lambda\), the scattering albedo \(\varpi_\lambda\), and the scattering asymmetry parameter \(g_\lambda\). The wavelengths must be listed in increasing or decreasing order. Property values outside of the tabulated wavelength range are clamped to the nearest border value. As a special-case consequence, if only a single wavelength is tabulated, the properties are considered to be constant for all wavelengths.

Because a basic dust mix such as this one is usually used in isolation and the dust distribution is normalized to a given optical depth or total dust mass, the value of the extinction coefficient is essentially scale free. This class uses a fixed arbitrary value of the dust mass per hydrogen atom, \(\mu=1.5\times 10^{-29} \text{kg}\,\text{H}^{-1}\) to set the absolute scale of the cross sections listed by some of the probes in relation to the mass coefficients.
