Please specify chemical species, line temperature, ionization stages, relative abundances (in mass fractions, preset values are solar) as well as your e-mail address. According to your input, TIRO will calculate bound-bound and bound-free absorption cross-sections based on Kurucz's data.


You will be notified by e-mail how to retrieve your data.

Frequency Grid

This TIRO calculation requires a frequency grid (plain text) in TMAP format. You can choose between the following options:


for synthetic spectra (POS data)

for model calculation (LIN data)

individual (300000 points maximum)


When publishing research making use of this tool, please acknowledge:
"The TIRO tool (http://astro.uni-tuebingen.de/~TIRO) used for this paper was constructed as part of the activities of the German Astrophysical Virtual Observatory."

Iron-Group Elements

The model atoms for the iron-group elements (here Ca - Ni) can individually be constructed for a single species or for a group of elements combined in a so-called generic model atom. For details see Rauch & Deetjen (2003).

Ionization Stages

Elements

The default solar element abundances are taken from Scott et al.(2015). They may be used, e.g., to calculate a generic model atom (see above) with elements in solar abundance relation.
