Scientific paper

Iron-group elements have a very high number of atomic levels and an overwhelming number of spectral lines. No NLTE model-atmosphere code can cope with these in a classical way. A statistical approach was developed over the last decade to decrease the number of levels and lines to a manageable amount. The Iron Opacity and Interface (IrOnIc) calculates sampled cross-sections and model-atom files as input for model-atmosphere computations. IrOnIc is presently transferred into a parallelized code to reduce the calculation time to a reasonable value. It will be accessible by the public as a service of the German Astrophysical Virtual Observatory.
