The MRNDustMix class represents a dust mixture consisting of silicate graphite and dust grains with optical properties taken from Bruce Draine's web site and with grain size distributions according to the well-known MRN power-law prescription (Mathis, Rumpl & Nordsieck 1977, ApJ, 217, 425). The actual coefficients for the size distributions are taken from Weingartner & Draine (2001, ApJ, 548, 296) on page 296, i.e.
\[ \frac{\text{d}n_\text{D}}{\text{d}a} / n_\text{H}= C\, a^{-3.5} \qquad \text{for}\quad a_\text{min} \leq a \leq a_\text{max}, \]
with \(C=10^{-25.13}\,\text{cm}^{2.5}\) for graphite and \(C=10^{-25.11}\,\text{cm}^{2.5}\) for silicate, and with \(a_\text{min}=50\,\text{\AA}\) and \(a_\text{max}=0.25\,\mu\text{m}\) for both grain populations.
For each of the populations, the user can configure the number of grain size bins used to discretize the thermal emission calculations for the dust mix.
The class uses the grain compositions defined in the DraineSilicateGrainComposition and DraineGraphiteGrainComposition classes, and the power-law size distribution defined in the PowerLawGrainSizeDistribution class.
