VizieR Online Data Catalog: Measured DIB 8620 (Zhao+, 2021)
Abstract
This catalog contains 2540 measurements of DIB 8620, of which 760 are measured in the spectra from the Gaia-ESO survey (GES; Gilmore et al., 2012Msngr.147...25G), and 1780 are from the the Giraffe Inner Bulge Survey (GIBS; Zoccali et al., 2014A&A...562A..66Z, Cat. J/A+A/562/A66). GES is a public spectroscopic survey targeting all the major components of the Milky Way with the purpose of characterizing the chemistry and the kinematics of these populations. We made use of the official public data release DR4 using the high-resolution grating HR21 centered at 8757 angstroms with a spectral resolution of 16,200 on the GIRAFFE spectrograph. The DIB features in the spectra were fitted by a Gaussian profile after subtracting the stellar components. The EW was then calculated by the fitted depth and width of the profile. The error of EW was estimated considering the contributions of both the random noise and the mismatches between the observed and synthetic spectra. The detailed description of DIB measurement in GIBS spectra can be found in Zhao et al., (2021A&A...645A..14Z, Cat. J/A+A/645/A14).
