A New Code for Comprehensive Self-Consistent Modelling of Planetary Nebula Luminescence

A new code PAN (Photoionized Axially-symmetrical Nebula) for the self-consistent modelling of a cylindrical gaseous nebula photoionized by a central source of ionizing radiation is developed. All of the processes which play an important role in the ionization and thermal equilibrium of the nebular gas are included in the code.
