Beginning of ReadMe : J/A+A/468/1115 Thorium and argon lines in the visible (Lovis+, 2007) ================================================================================ A new list of thorium and argon spectral lines in the visible. Lovis C., Pepe F. <Astron. Astrophys. 468, 1115 (2007)> =2007A&A...468.1115L ================================================================================ ADC_Keywords: Atomic physics ; Spectroscopy Keywords: atomic data - techniques: spectroscopic - atlases - catalogs Abstract: We 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. Description: This thorium and argon line list has been derived from ThAr spectra obtained with the HARPS instrument at the ESO-3.6m telescope at La Silla Observatory. It contains the updated wavelengths of 8442 lines between 3785 and 6915AA, with a typical accuracy of 10m/s (3.3 parts in 10^8^ or 0.18mAA). Line intensities, previously-known wavelengths and identifications are also provided.
