Citing this table

This table has an associated publication. If you use data from it, it may be appropriate to reference 2009ApJS..184..218L (ADS BibTeX entry for the publication) either in addition to or instead of the service reference.

To cite the table as such, we suggest the following BibTeX entry:

@MISC{vo:zcosmos_20k_spec,
  year=2020,
  title={{zCOSMOS} 20k Bright Spectra},
  author={Lilly et al.},
  url={https://vo.lam.fr/tableinfo/zcosmos_20k.spectra},
  howpublished={{VO} resource provided by the {CeSAM} Virtual Observatory Server}
}

Resource Documentation

zCOSMOS is a large redshift survey undertaken in the COSMOS field using the VIMOS spectrograph mounted at the Melipal Unit Telescope of the VLT at ESO's Cerro Paranal Observatory, Chile.

This resource contain the 20,689 spectra of the DR3 release.

NOTES

To the original zCOSMOS spectra, we added to the primary header the Z_SPEC keyword with the spectroscopic redshift and the CC one with the Confidence Class.

ACKNOWLEDGEMENTS

When using data products provided in this release, acknowledgement should please be given in the text to the zCOSMOS project, referring to this release and Lilly et al. 2009, ApJS, 184, 218 until superseded by a later version.

Please also make sure that the following statement appears in your acknowledgements when using these data:

Based on zCOSMOS observations carried out using the Very Large Telescope at the ESO Paranal Observatory under Programme ID: LP175.A-0839.
