GIRAFFE Inner Bulge Survey (GIBS). I.
Listed in IVOA Registry (Virtual Observatory)
The Galactic bulge is a massive, old component of the Milky Way.
Description
It is known to host a bar, and it has recently been demonstrated to have a pronounced boxy/peanut structure in its outer region. Several independent studies suggest the presence of more than one stellar populations in the bulge, with different origins and a relative fraction changing across the bulge area.
This is the first of a series of papers presenting the results of the Giraffe Inner Bulge Survey, carried out at the ESO-VLT with the multifibre spectrograph FLAMES. Spectra of ~5000 red clump giants in 24 bulge fields have been obtained at resolution R=6500, in the infrared Calcium triplet wavelength region at ~8500{AA}. They are used to derive radial velocities and metallicities, based on new calibration specifically devised for this project.

Radial velocities for another ~1200 bulge red clump giants, obtained from similar archive data, have been added to the sample. Higher resolution spectra have been obtained for ~450 additional stars at latitude b=-3.5, with the aim of investigating chemical abundance patterns variations with longitude, across the inner bulge. In total we present here radial velocities for 6494 red clump stars.
We present here the target selection criteria, observing strategy and the catalogue with radial velocity measurements for all the target stars.
