Abstract : Documentation accompanying the Barber and Hill T-matrix codes for scattering by axisymmetric particles is incomplete regarding the size of particles to which it is applicable. We have calculated the convergence parameters for many spheroidal particles with a variety of sizes, aspect ratios, and refractive indices to indicate the range of particles that are amenable to Barber and Hill's code. To expedite the calculations, the T-matrix program was modified so that it determines convergence parameters without the normal trial and error interaction with the user.
