This first release of CORALIE data contains the spectra of the historical radial-velocity planet-search programme carried out by the Geneva Observatory exoplanet team with the CORALIE spectrograph on the Euler 1.2m telescope at La Silla. CORALIE covers 390 to 690 nm at a resolving power of R ≈ 60000. Fibre A is placed on the target, while fibre B records a simultaneous ThAr (before June 2015) or Fabry-Perot reference, or the sky. Instrument upgrades in 2007 and 2014 introduced radial-velocity zero-point offsets, so the release contains spectra from three instrument versions (CORALIE98, CORALIE07 and CORALIE14) and stops at the 2024 intervention.
First Data Release of the CORALIE Historical Planet-search Programme
Published: 11 Nov 2026
The primary products are wavelength-calibrated, barycentric-corrected 1D spectra with merged echelle orders (not flux calibrated), accompanied by 2D order-by-order spectra, fibre B spectra, drift matrices and cross-correlation functions. Radial velocities are stored in the product headers. In total, the release includes 65,502 observations of around 1700 targets. Further details on the observations, data reduction and known limitations are provided in the accompanying release documentation.
The spectra are available via the Archive Science Portal or Programmatically. The DOI associated to this Phase3 data collection is doi.org/10.18727/archive/106.
