VANDELS data

The current data release (DR2) consists of spectra obtained during the first two VANDELS observing seasons, ESO run numbers: 194.A-2003(E-Q), which ran from Aug 2015-Jan 2016 and Aug 2016-Jan 2017, respectively. The data release includes the spectra for all galaxies for which the scheduled integration time was completed during the first two seasons. In addition, the data release also includes the spectra for those galaxies for which the scheduled integration time was 50% complete at the end of season two (i.e. 20/40 hours and 40/80 hours). The total number of spectra released is 1362 (586 in CDFS and 776 in UDS).

data access

vandels consortium database

We provide access through a dedicated database, accessible at this LINK (free registration required)

Spectra are stored as multi-extension FITS files containing the following extensions;

Primary: the 1D extracted spectrum
EXR2D: the 2D linearly resampled spectrum
SKY: the 1D sky spectrum
NOISE: the 1D noise estimate
EXR1D: a copy of the 1D extracted spectrum (to recover any edit that might be done on the Primary)
THUMB: the image thumbnail of the object
BLUE-CORR: the correction that was applied to the originally calibrated spectra, due to a systematic drop in flux at the very blue end of the spectra, compared to the available broad band photometry (see Pentericci et al. 2018 for more details)

Each extension can be viewed using standard tools like IRAF or IDL. The full information stored in these files can be inspected as a whole using the pandora.ez software as shown in this SCREENSHOT. If you want to install this tool follow the instructions at this LINK
