| Description |
The VANDELS ESO public spectroscopic survey uses VLT/VIMOS to obtain ultra-deep, medium resolution, optical spectra of high-redshift galaxies within the UKIDSS Ultra Deep Survey (UDS) and Chandra Deep Field South (CDFS) survey fields. This DR2 catalog provides the measured redshifts for the 1362 galaxies for which enough integration time was reached till August 2017.
