%%% Light Scattering by Spheroidal Particles
%%% ========================================
%%%
%%% Calculations of extinction, scattering and absorption
%%% efficiency factors for prolate or oblate homogeneous spheroids.
%%%
%%%
%%% Parameters:
%%% -----------
%%%
%%% nterms: number of terms in Eqs. for efficiency factors,
%%% nalphas: number of angles for incident radiation.
%%%
%%% The values of parameters may be changed in file h4_3q2a.for.
%%%
%%%
%%% Restrictions:
%%% -------------
%%%
%%% nterms:
%%% c2 = ri*(2*pi/wvl)*(d/2) <= 135 (?) for prolate spheroids,
%%% <= 100 (?) for oblate spheroids,
%%% (d - focus distance of spheroid),
%%%
%%% nterms ~= 1.2 * cdabs(c2) + 8 (+ ~30 if ksi0 > 2).
%%%
%%% nalphas: <= 91
%%%
%%%
%%% Recommended values:
%%% -------------------
%%%
%%% refractive index: k <= 1/2*n, (?)
%%% eps: 1d-15 for prolate spheroids,
%%% 1d-15 for oblate spheroids,
%%% eps1: 1d-3 - 1d-6
