The VANDELS ESO public spectroscopic survey: Final data release of 2087 spectra and spectroscopic measurements

VANDELS is an ESO Public Spectroscopic Survey designed to build a sample of high-signal-to-noise ratio, medium-resolution spectra of galaxies at redshifts between 1 and 6.5. Here we present the final Public Data Release of the VANDELS Survey, comprising 2087 redshift measurements. We provide a detailed description of sample selection, observations, and data reduction procedures. The final catalogue reaches a target selection completeness of 40% at i(AB)=25. The high signal-to-noise ratio of the spectra (above 7 in 80% of the spectra) and the dispersion of 2.5 angstrom allowed us to measure redshifts with high precision, the redshift measurement success rate reaching almost 100%. Together with the redshift catalogue and the reduced spectra, we also provide optical mid-infrared photometry and physical parameters derived through fitting the spectral energy distribution. The observed galaxy sample comprises both passive and star forming galaxies covering a stellar mass range of 8.3 < Log(M-*/M-circle dot) < 11.7.

Automated summary

VANDELS is an ESO Public Spectroscopic Survey designed to create a sample of high signal-to-noise ratio, medium-resolution spectra of galaxies at redshifts between 1 and 6.5. The final Public Data Release includes 2087 redshift measurements, with high precision in measuring redshifts being a key feature of the survey.
