cds-question@unistra.fratomic-physicsspectroscopyWe present a new list of thorium and argon emission lines in the visible obtained by analyzing high-resolution (R=110000) spectra of a ThAr hollow cathode lamp. The aim of this new line list is to allow significant improvements in the quality of wavelength calibration for medium- to high-resolution astronomical spectrographs. We use a series of ThAr lamp exposures obtained with the HARPS instrument (High Accuracy Radial-velocity Planet Searcher) to detect previously unknown lines, perform a systematic search for blended lines and correct individual wavelengths by determining the systematic offset of each line relative to the average wavelength solution.2007A&A...468.1115Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/468/1115CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/468/1115https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/468/1115http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/468/1115https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/468/1115https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/468/1115http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/468/1115GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/468/1115/table1Thorium and argon line listIDLine identification (1)phys.atmol.ionStagecharrecnoRecord number assigned by the VizieR team.
