TabulatedDustMix is an abstract class for representing basic dust mixes described by tabulated properties for a single representative grain using the Henyey-Greenstein scattering mode.
Specifically, the tabulated properties include the extinction mass coefficient \(\kappa^\text{ext}_\lambda\), the scattering albedo \(\varpi_\lambda\) and the scattering asymmetry parameter \(g_\lambda\), as a function of wavelength \(\lambda\). 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. Still, the dust mass per hydrogen atom \(\mu\) may be specified to set the absolute scale of the property, so that the cross sections listed by some of the probes have an appropriately scaled value.
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.
The subclass must load the tabulated data, and this abstract class handles everything else.
This item type is allowed only if the Boolean expression "!StochasticDustEmission" evaluates to true after replacing the names by true or false depending on their presence.
This item type is displayed only if the Boolean expression "Level2" evaluates to true after replacing the names by true or false depending on their presence.

This function must be implemented in each subclass to store the wavelengths and the corresponding tabulated properties in the array arguments, and to return the dust mass per hydrogen atom. The function must guarantee that all arrays have the same size. The wavelengths must be listed in increasing or decreasing order.
Implemented in MeanFileDustMix, and MeanListDustMix.

This function is invoked by the DustMix base class to obtain the representative grain optical properties for this dust mix. The first argument specifies the wavelength grid on which the absorption and scattering cross sections and the asymmetry parameter must be tabulated. The second argument is not used. The function store these tabulated properties into the three subsequent output arrays, which will already have the same length as the input wavelength grid when the function gets called. The Mueller matrix tables remain untouched. Finally, the function returns the dust mass per hydrogen atom for the dust mix.
This function in turn invokes the getDustProperties() function that must be implemented by each TabulatedDustMix subclass, and it subsequently resamples the returned properties on the requested wavelength grid.
Implements DustMix.
