Nature of problem:
In the core of high temperature cylindrical electric arcs a net radiative flux of energy occurs in the outward radial direction. The code described here calculates the radiative flux within a frequency range and at a radial position which are user-specified, taking account of continuum and line radiation and the N2 (Birge-Hopfield no.2) molecular band radiation. The spectral data used is for nitrogen.

Restrictions:
The model assumes conditions for LTE are satisfied.

Running time:
A frequency range covering 20-25 absorption coefficient maxima (lines or multiplets) takes about 170 s.
