cds-question@unistra.fratomic-physicsA comprehensive set of accurate atomic data is required for analyses of astrophysical and solar spectra. CHIANTI provides a database of atomic energy levels, wavelengths, radiative data and electron excitation data for ions which are abundant in cosmic plasmas. The most recent electron excitation data have been assessed and stored following the method of Burgess & Tully (1992A&A...254..436B). The current version is essentially complete for specifying the emission spectrum at wavelengths greater than 50{AA}. A list of observed lines in the spectral region between 50 and 1100{AA} has been compiled and compared with the lines predicted by the CHIANTI database. The CHIANTI database reproduces the vast majority of lines observed at these wavelengths. CHIANTI includes IDL (Interactive Data Language) routines to calculate optically thin synthetic spectra for equilibrium conditions. IDL routines to calculate theoretical line intensities required for electron density or temperature diagnostics and emission measure studies are also included. The CHIANTI atomic database and supporting IDL routines are available by anonymous FTP.1997A&AS..125..149Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/125/149CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/370/1071 : Fe XII UV line intensity ratios (Binello+, 2001)http://wwwsolar.nrl.navy.mil/chianti.html : CHIANTI homepagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/125/149https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/125/149http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/125/149https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/125/149https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/125/149http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/125/149GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+AS/125/149/table3A list of observed lines and lines in the CHIANTI database between 50 and 1100 AngstromsrecnoRecord number assigned by the VizieR team.
