The first public data release of the HARPS Radial Velocities Catalog contains measurements obtained from 2003 to 2023 with the High Accuracy Radial Velocity Planet Searcher (HARPS) spectrograph installed at the ESO 3.6m telescope in La Silla Observatory (Chile). The catalog comprises 289843 observations of 6488 unique astronomical objects. A total of 282294 radial velocities are reported in this catalog and are obtained using the HARPS pipeline (typical precision of 0.5 m/s) and 288972 independent radial velocities that are measured on the H_alpha spectral line (typical error of around 300 m/s).
First Data Release of HARPS Radial Velocity Catalog
Published: 12 Dec 2023
Each observed target has been cross-matched with SIMBAD database to ensure accurate identification. Information provided for each target includes: astrometric parameters (coordinates, parallaxes, proper motions, radial velocities), photometric parameters (apparent magnitudes in the visible and near-infrared), spectral types and object classifications.
The catalog containing radial velocities is available from the ESO Archive Science Portal, the Programmatic Access service, or via the dedicated Catalogue Interface.
More details about the release content can be found in the associated data release description. A DOI is assigned to the data collection.
