ModifiedLogNormalGrainSizeDistribution is a GrainSizeDistribution subclass that represents a modified log-normal dust grain size distribution of the form
\[ \frac{\text{d}n_\text{D}}{\text{d}a} \propto \frac{1}{a} \,\exp\left[ - \frac{(\ln(a/a_0))^2}{2\sigma^2} \right] \, M(a) \qquad \text{for}\quad a_\text{min} \leq a \leq a_\text{max} \]
with a mixing term
\[ M(a) = y_0 + (y_1-y_0)\frac{\ln(a/a_\text{min})}{\ln(a_\text{max}/a_\text{min})}. \]
The size range of the distribution can be configured in the RangeGrainSizeDistribution base class. The centroid \(a_0\) and the width \(\sigma\) can be configured in the LogNormalGrainSizeDistribution base class. The remaining two parameters \(y_0\) and \(y_1\) can be configured as attributes in this class. The function is scaled arbitrarily.
The functional form for the grain size distribution implemented by this class is inspired by the DustEM code, which is described in Compiègne et al. 2011 (AA, 525, A103) and can be downloaded from http://www.ias.u-psud.fr/DUSTEM/.
