VizieR Online Data Catalog: Bright VPM stars from Gaia RVS spectra (Viswanathan+, 2024)
Abstract
Catalogue of very metal-poor stars selected and analysed using the Gaia DR3 RVS spectra. This table consists of the following columns: DR3/EDR3 source_ids of sources, positions in equatorial coordinates (RA, Dec in degrees) in J2016 format, Gaia G, BP, and RP magnitudes, parallax and parallax uncertainty from Gaia DR3 (parallax, parallax_error in mas), signal-to-noise ratio of the renormalised Gaia RVS spectra, radial velocity offset from the rest frame and its uncertainty (voffset and dvoffset in km/s), equivalent widths of the three Calcium Triplet lines and errors on them (in nm), inferred spectroscopic metallicities and errors on them.
