Fig. 4

Albedo based on the size-averaged scattering and extinction cross-section assuming an MRN distribution as a function of the maximum grain size for silicate and graphite (Draine & Lee 1984). The dotted line indicates the limiting grain size where the error due to neglecting the phase function in the scattering integral is less than 30%.
