Abstract:
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 iAB=25. The high
signal-to-noise ratio of the spectra (above 7 in 80% of the spectra)
and the dispersion of 2.5Å 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☉)<11.7.
Description:
We present the final public data release of the VANDELS survey, which
includes 2087 redshifts of galaxies in the range 1<z<6.
The VANDELS survey spans the redshift range 1<z<6.5, with a target
sampling rate greater than 45% for passive galaxies down to
iAB=24.5 and for SF galaxies down to iAB=24. The
spectroscopic measurement success rate is as high as 98% considering
all redshift measurements, and 86% considering only redshifts with a
reliability above 80%. By internal comparison between different
observations, we estimate a redshift accuracy of 0.0007.
All catalogues and spectra are accessible through the survey database
(http://vandels.inaf.it) where all information can be queried
interactively, and via the ESO Archive (https://www.eso.org/qi/).
