cds-question@unistra.frgalaxy-planesmilky-way-galaxymetallicityradial-velocityWe observe red clump stars in four fields along the Galactic bar major axis (l=10{deg}, -6{deg}, 6{deg} and b=0{deg}, plus a field at l=0{deg}, b=1{deg}) with low-resolution spectroscopy from FLAMES/GIRAFFE (setup LR08) at the VLT, observing around the CaII triplet. We developed robust methods to extract radial velocity and metallicity estimates from these low signal-to-noise spectra. Results have been derived by fixing atmospheric parameters typical of a red clump star (Teff=4750K, logg=2.5). For some targets, the metallicity could not be derived.2014A&A...563A..15Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/563/A15CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/349/1059 : OGLE variables in Galactic bar (Wray+, 2004)J/ApJ/691/1387 : Spectroscopy of the Galactic bar.
