Calculates maximum and area equivalent diameters from volume equivalent diameter.

This is primarily a help function for using the T-matrix method and only a few particle shapes are handled. For shapes handled and further comments on the input arguments, see scat_data_singleTmatrix().

Area equivalent diameter is the equivalent sphere diameter corresponding to the “maximum axial area”. This is the largest cross-sectional area of the particle, observed either along the particle’s main axis or in the perpendicular direction. That is, for a cylinder having diameter d and thickness h, this area is either (pi*d^2)/4 or (h*d).
