TOSS -- Tübingen Oscillator Strengths Service

This service provides oscillator strengths and transition probabilities.
Mainly based on experimental energy levels, these were calculated with the
pseudo-relativistic Hartree-Fock method including core-polarization
corrections.
When publishing research making use of this tool, please acknowledge:
"The TOSS service (http://dc.g-vo.org/TOSS) used for this paper
was constructed as part of the activities of the German Astrophysical
Virtual Observatory."

A table of transitions, their species, and
their properties.
A view on top of toss.data that
has values in conventional units and with air wavelengths
(rather than vacuum) between 2000 and 20000 Ångstrøm.

TOSS legacy
Tübingen Oscillator Strengths Service Form Interface
TOSS data is also available in a form
compliant to the IVOA spectral line data model in a
\RSTservicelink{toss/q/q/info}{SLAP service} and within our TAP
service (\RSTservicelink{toss/q/examples}{usage examples}).
static
A legacy interface (conventional
units, air wavelength around the optical range) to
TOSS data is also available at
\RSTservicelink{toss/q/legacy/form}. See also
\RSTservicelink{toss/q/examples}{usage examples} for how to do
TAP queries on this data.
