cds-question@unistra.frinterstellar-mediumline-intensitiesWe developed a set of procedures to automatically detect and measure the DIB around 8620{AA} (the Gaia DIB) for a wide range of temperatures. The method was tested on about 5000 spectra from the Giraffe Inner Bulge Survey (GIBS; Zoccali et al., 2014A&A...562A..66Z), and 4194 reasonable fitting results were got. We made use of the reddenings, E(J-Ks), from the extinction map developed by Surot et al. (2020arXiv201002723S). A linear correlation between the equivalent width (EW) and E(J-Ks) was derived as E(J-Ks)/EW = 1.875, according to E(B-V)/EW = 2.721, which is highly consistent with previous results toward similar sightlines. After a correction based on the Vista Variables in the Via Lactea (VVV; Minniti et al., 2010NewA...15..433M) database for both EW and E(J-Ks), the coefficient derived from individual GIBS fields, E(J-Ks)/EW=1.884, is also in perfect agreement with literature values. Based on a subsample of 1015 stars toward the Galactic center, we determined a rest-frame wavelength of the Gaia DIB as 8620.55{AA}. A Gaussian profile is proved to be a proper and stable assumption for the Gaia DIB as no intrinsic asymmetry is found.2021A&A...645A..14Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/645/A14CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/348 : VISTA Variable in the Via Lactea Survey DR2 (Minniti+, 2017)J/A+A/562/A66 : GIRAFFE Inner Bulge Survey (GIBS).
