cds-question@unistra.fratomic-physicspolarimetryIn this paper we provide extensive tables of the coefficients that are needed in the calculation of the second-order moments of the polarization profiles of hydrogen lines. We cover all the transitions up to the level n=50, which is enough for many astrophysical applications. We also provide formulae which allow the calculation of the line and oscillator strengths and of the Einstein coefficients for the tabulated transitions.1995A&AS..114..363Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/114/363CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/114/363https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/114/363http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/114/363https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/114/363https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/114/363http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/114/363GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+AS/114/363/tableCoefficients needed in the calculation of the second-order moments of the Stokes profiles of optically-thin, emission hydrogen lines + other related coefficientsrecnoRecord number assigned by the VizieR team.
