Abstract

The authors present a complete atomic model for Mg I line synthesis, where all the atomic parameters are based on recent experimental and theoretical data. It is studied how the computed profiles at 4571 Å and 5173 Å are influenced by the choice of these parameters and the number of levels included in the model atom. The authors also present observed profiles of the lambda5173 Å b2 line and theoretical profiles for comparison based on a recent atmospheric model for the average quiet Sun.
