Advanced Three Level Approximation for
Numerical Treatment of Cosmological Recombination: atlant 1.0
New public numerical code for fast calculations of
cosmological recombination of primordial hydrogen-helium plasma is
presented. This code is based on the three-level approximation (TLA) model
of recombination and allows us to take into account some ``fine''
physical effects of cosmological recombination simultaneously with
using fudge factors.
