Tübingen Oscillator Strengths Service Form Interface

TOSS data is also available in a form compliant to the IVOA spectral line data model in a SLAP service and within our TAP service (usage examples).

Conventional wavelength of the transition. This is the air wavelength between 2000 and 20000 Angstrom, the vacuum wavelength otherwise.
No selection matches all, multiple values legal.
