cds-question@unistra.frgalaxiesspectroscopyphotometryredshiftedThe K20 survey is a near infrared-selected, deep (Ks<20) redshift survey targeting galaxies in two independent regions of the sky, the Chandra Deep Field South and the field around the quasar 0055-2659, for a total area of 52arcmin^2^. The total Ks-selected sample includes 545 objects. Low-resolution (R~300-600) optical spectra for 525 of them have been obtained with the FORS1/FORS2 spectrographs at the ESO/VLT, providing 501 spectroscopic identifications (including 12 type-1 AGN and 45 stars); consequently, we were able to measure redshifts and identify stars in 96% of the observed objects, whereas the spectroscopic completeness with respect to the total photometrically selected sample is 92% (501/545). The K20 survey is therefore the most complete spectroscopic survey of a near infrared-selected sample to date. The K20 survey contains 444 spectroscopically identified galaxies, covering a redshift range of 0.05<z<2.73, with a mean redshift <z>=0.75; excluding the 32 "low-quality" redshifts does not significantly change these values.2005A&A...437..883Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/437/883CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/392/395 : Ks-band magnitudes of the K20 sample (Cimatti+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/437/883https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/437/883http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/437/883https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/437/883https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/437/883http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/437/883GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/437/883/catalog (K20 redshift survey results: CDFS and QSO 0055-2659 fields)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/437/883/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/437/883/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/437/883/catalog?GETtext/xml+votable180.050000true53.13231667-27.810933330.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/437/8836/16656 359357.952274030004205e-20 1.0188844282367877e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/437/883?format=asciidefaultJ/A+A/437/883/catalogK20 redshift survey results: CDFS and QSO 0055-2659 fieldsrecnoRecord number assigned by the VizieR team.
