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
  • EXR1D_UNCORR: the original 1D spectrum without 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
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
