cds-question@unistra.frgalaxiesinfrared-sourcesinfrared-photometryWe present an ultradeep K_s_-band image that covers 0.5x0.5deg^2^ centered on the Great Observatories Origins Deep Survey-North (GOODS-N). The image reaches a 5{sigma} depth of K_s,AB_=24.45 in the GOODS-N region, which is as deep as the GOODS-N Spitzer Infrared Array Camera (IRAC) 3.6um image. We present a new method of constructing IRAC catalogs that uses the higher spatial resolution K_s_ image and catalog as priors and iteratively subtracts fluxes from the IRAC images to estimate the IRAC fluxes. Our iterative method is different from the {chi}^2^ approach adopted by other groups. We verified our results using data taken in two different epochs of observations, as well as by comparing our colors with the colors of stars and with the colors derived from model spectral energy distributions of galaxies at various redshifts. We make available to the community our WIRCam K_s_-band image and catalog (94951 objects in 0.25deg^2^), the Interactive Data Language pipeline used for reducing the WIRCam images, and our IRAC 3.6-8.0um catalog (16950 objects in 0.06deg^2^ at 3.6um). With this improved K_s_ and IRAC catalog and a large spectroscopic sample from our previous work (Cat. <J/ApJ/689/687>), we study the color-magnitude and color-color diagrams of galaxies. We compare the effectiveness of using K_s_ and IRAC colors to select active galactic nuclei and galaxies at various redshifts. We also study a color selection of z=0.65-1.2 galaxies using the K_s_, 3.6um, and 4.5um bands.2010ApJS..187..251Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/187/251CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/640/603 : Catalog of AGNs in the GOODS fields (Treister+, 2006)J/ApJ/689/687 : GOODS-N spectroscopic survey (Barger+, 2008)J/ApJ/697/1369 : GOODS Ks-selected multiwavelength compilations (Bundy+, 2009)http://www.asiaa.sinica.edu.tw/~whwang/goodsn_ks/ : Ultradeep Ks imaging inhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/187/251https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/187/251http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/187/251https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/187/251https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/187/251http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/187/251GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/187/251/catalog (The full catalog (K_s_ selected, plus 358 sources without K_s_ counterparts))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/187/251/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/187/251/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/187/251/catalog?GETtext/xml+votable180.050000true188.9532738961.9286250.0055555555555555566/11227 11230 11249 112522.0616683193919197e-20 6.185923063528282e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/187/251?format=asciiInfrareddefaultJ/ApJS/187/251/catalogThe full catalog (K_s_ selected, plus 358 sources without K_s_ counterparts)recnoRecord number assigned by the VizieR team.
