It creates simulations by accurately tracing up to several million light rays through mathematical models of ice crystals. Select from ready to run simulations of common and rare halos with text descriptions. Halos from all crystals are simulated; hexagonal plates, columns, pyramidals and non water-ice crystals which might be found in other planetary atmospheres. Files for plate, singly oriented columns, Parry and Lowitz orientations included. Others can be generated. Axial dispersions and dispersion distributions can be specified. All the possible light paths through crystals are sampled, hence all halos for a given solar altitude and crystal type/alignment are simulated.
