The coefficients of the parameterizations are given in the tables below. Each
file has at least six columns of information. The first is a string describing the
particle habit. The second is the wavelength (microns). The third through
sixth are the *a*, *b*, or *c* coefficients in the equations
given on the main page, e.g., *a*_{0}, *a*_{1}, *a*_{2},
*a*_{3}. The units are m^{3} g^{-1} km^{-1} for
b_{ext}/*WC*. The single-scattering
albedo and asymmetry parameter are unitless.

The asymmetry parameter file has two additional columns, the first of which
(the seventh column) is the second asymmetry parameter *g*_{2} for the double
Henyey-Greenstein (H-G) function. The last column is the weighting factor
*f* in the double H-G.
