 often $R(V) = A(V)/E(B-V)$ which is the ratio of total to selective extinction.
 \autoref{fig:parameter_averages} shows examples of such models. The Grain odels
 are those extinction curves computed using dust grain models

 Shapes that provide flexible functional forms that fit selected wavelength
 ranges (see \autoref{fig:shapes} for examples).
