cds-question@unistra.frsurveysinfrared-photometryvisible-astronomystellar-massesWe present the curation and verification of a new combined optical and near infrared dataset for cosmology and astrophysics, derived by combining ugri-band imaging from the Kilo-Degree Survey (KiDS) and ZYJHKs-band imaging from the VISTA Kilo degree Infrared Galaxy (VIKING) survey. This dataset is unrivaled in cosmological imaging surveys due to the combination of its area (458 deg2 before masking), depth (r<=25), and wavelength coverage (ugriZYJHKs). This combination of survey depth, area, and (most importantly) wavelength coverage allows significant reductions in systematic uncertainties (i.e. reductions of between 10% and 60% in bias, outlier rate, and scatter) in photometric-to-spectroscopic redshift comparisons, compared to the optical-only case at photo-z above 0.7. The complementarity between our optical and near infrared surveys means that over 80% of our sources, across all photo-z, have significant detections (i.e. not upper limits) in our eight reddest bands. We have derived photometry, photo-z, and stellar masses for all sources in the survey, and verified these data products against existing spectroscopic galaxy samples. We demonstrate the fidelity of our higher-level data products by constructing the survey stellar mass functions in eight volume-complete redshift bins. We find that these photometrically derived mass functions provide excellent agreement with previous mass evolution studies derived using spectroscopic surveys. The primary data products presented in this paper are made publicly available through the KiDS survey website.2019A&A...632A..34Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/632/A34CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/343 : VIKING catalogue data release 2 (Edge+, 2016)II/344 : KiDS-ESO-DR2 multi-band source catalog (de Jong+, 2015)II/347 : KiDS-ESO-DR3 multi-band source catalog (de Jong+, 2017)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/632/A34https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/632/A34http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/632/A34https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/632/A34https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/632/A34http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/632/A34GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/632/A34/catalog (LePhare MASS_BEST values for KiDS+VIKING-450 sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/632/A34/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/632/A34/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/632/A34/catalog?GETtext/xml+votable180.050000true359.6305018-31.711777430.0055555555555555564/1032 1365 1621-1622 1642 1685 1706 2243-2244 2248 2911 2931-2932 5/1024-1026 2048 2050 4109-4111 4132 4136 4138 5459 5468-5469 6397-6399 6477-6479 6481-6483 6492-6494 6500-6501 6503 6505 6512-6514 6561-6564 6566 6572-6574 6737-6739 6744-6745 6747-6750 6758 6761-6762 6819 6828 6830 6912-6914 7845-7846 7850 8823 8828-8829 8831 8907 8967 8971 8982 8984-8986 8996-8998 10239 11262-11263 11639 11643 11719 11732-11734 11736-11738 11745-11747 11749 11752 11760 6/4108-4110 4112-4114 4128-4130 8198 8204 8206 8224-8226 16407 16412-16413 16415 16429-16431 16433-16435 16450 16456 16482 16532-16534 16536-16538 16548-16550 16556 16896 21829-21831 21833 21835 21860-21861 21863 21880-21881 21884-21885 25565-25567 25581-25583 25585-25587 25885-25887 25901-25903 25905-25907 25921-25923 25980-25982 25988-25989 25998-25999 26009 26017 26028-26029 26036-26037 26039 26060-26062 26064-26066 26080-26082 26158-26159 26189-26191 26202 26213 26224 26241-26243 26260 26262 26268 26270-26271 26300-26302 26336 26338 26879 26909 26911 26943 26945-26947 26985-26987 27004-27006 27023 27029 27031 27036 27038 27043 27052-27054 27056-27058 27072-27074 27088-27089 27221 27223 27270-27271 27273-27275 27288 27290-27291 27316 27318-27319 27324-27326 27392-27394 27660-27662 27664-27666 27680-27682 31293-31295 31336 31338-31339 31373 31375 31377-31379 31388-31390 31393-31395 31397-31399 31404 31408-31410 31424-31426 34539-34540 34542-34543 35287 35291 35320-35321 35323 35627 35665 35668-35669 35716 35863 35867 35879 35922-35923 35948 35952 35996 36000-36002 36008 36010 36016 36032 36352 40949-40951 40953-40955 45037-45039 45042-45043 45046 46551 46555 46567 46571 46813 46815 46837 46871 46875 46893-46895 46940 46956-46957 46960 46962 46968 46977-46979 46992-46993 46995 47000 47002 47012-47014https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/632/A34?format=asciiOpticalInfrareddefaultJ/A+A/632/A34/catalogLePhare MASS_BEST values for KiDS+VIKING-450 sourcesrecnoRecord number assigned by the VizieR team.
