J/A+A/418/1073   Emission lines in optical spectrum of 3 Cen A (Wahlgren+, 2004)

Emission lines in the optical spectrum of 3 Cen A. Wahlgren G.M., Hubrig S. <Astron. Astrophys. 418, 1073 (2004)> =2004A&A...418.1073W
ADC_Keywords: Abundances ; Equivalent widths ; Spectroscopy ; Stars, peculiar Keywords: line: identification - stars: abundances - stars: chemically peculiar - stars: emission - stars: individual: 3 Cen A Description: Weak emission lines in the optical spectrum of the helium-weak chemically peculiar star 3 Cen A are tabulated. The observed wavelengths, line identification information and equivalent widths are presented based on data obtained with the ESO 1.5m telescope and FEROS instrument (16-17 May 2000) and the VLT with UVES spectrograph (24 June 2001). Table 2 is a listing of all recorded emission lines arranged by wavelength and including unidentified features. Table 3 arranges the identified lines according to their ion and multiplet.

Note (1): Identification uncertainty indicator. The presence of a colon indicates that the identification for the observed feature has a high uncertainty.
Global notes: Note (G1): Equivalent widths given pertains to the FEROS spectrum and the VLT/UVES instrument. nd: no data from this telescope fi: line filled-in, but note to continuum level al: line filled-in at continuum level b: equivalent width of absorption line c: measurement affected by terrestrial absorption line ..: feature not observed Note (G2): Synthetic spectrum absorption line depth, 1.000 is continuum level
