cds-question@unistra.frgalaxiesphotometryinfrared-photometryredshiftedspectroscopyWe present spectra and multicolor (B,I,K) data for near-infrared (K) selected spatially complete magnitude limited (K<20) galaxy samples from the Hawaii Survey. The redshift identification of the sample of 298 galaxies is substantially complete to a B magnitude of 26 and an I magnitude of 22.5, and identification of observed galaxies ranges from nearly 100% completeness at K<18 to ~70% completeness at K=19-20. We note that many of the unidentified objects appear to be red (I-K) objects which are flat in the optical and spectroscopically featureless. Strengths of spectral-line features and breaks are tabulated for the 262 galaxies with reasonably secure redshifts. The measured redshifts nearly all fall at z<1, with the exception of a compact absorption-line object at z=2.35. At K>=18, the redshift distribution is well fitted by a model with no luminosity evolution, implying that from the K-band Hubble diagram, the Hubble constant can vary at most by 10% over the redshift range from z~0.025 to 0.25, and that positive luminosity evolution at any significant level between z=0 and z=1 is ruled out. However, the evolution of both the emission-line strengths and the 4000{AA} break indicates that galaxies were undergoing significantly more star formation at z=1 than at the present time.1994ApJS...94..461Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/94/461CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/94/461https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/94/461http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/94/461https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/94/461https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/94/461http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/94/461GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/ApJS/94/461/table3Redshift catalog for all fields sorted by K magnituderecnoRecord number assigned by the VizieR team.
