cds-question@unistra.frinfrared-photometryvisible-astronomyWide-band photometrygalaxiescatalogsextinctionredshiftedThe Kilo-Degree Survey (KiDS) is an ongoing optical wide-field imaging survey with the OmegaCAM camera at the VLT Survey Telescope. It aims to image 1500 square degrees in four filters (ugri). The core science driver is mapping the large-scale matter distribution in the Universe, using weak lensing shear and photometric redshift measurements. Further science cases include galaxy evolution, Milky Way structure, detection of high-redshift clusters, and finding rare sources such as strong lenses and quasars. Here we present the third public data release (DR3) and several associated data products, adding further area, homogenized photometric calibration, photometric redshifts and weak lensing shear measurements to the first two releases. A dedicated pipeline embedded in the Astro-WISE information system is used for the production of the main release. Modifications with respect to earlier releases are described in detail. Photometric redshifts have been derived using both Bayesian template fitting, and machine-learning techniques. For the weak lensing measurements, optimized procedures based on the THELI data reduction and lensfit shear measurement packages are used. The multi-band catalogue, including homogenized photometry and photometric redshifts, covers the combined DR1, DR2 and DR3 footprint of 440 survey tiles (447deg^2^). Limiting magnitudes are typically 24.3, 25.1, 24.9, 23.8 (5 sigma in a 2 arcsec aperture) in ugri, respectively, and the typical r-band PSF size is less than 0.7 arcsec. The photometric homogenization scheme ensures accurate colors and an absolute calibration stable to ~2% for gri and ~3% in u. Separately released are a weak lensing shear catalogue and photometric redshifts based on two different machine-learning techniques.2017A&A...604A.134Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/II/347CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/344 : KiDS-ESO-DR2 multi-band source catalog (de Jong+, 2015)http://kids.strw.leidenuniv.nl/DR3/ : KiDS Data Release 3 home pagehttp://eso.org/rm/publicAccess#/dataReleases : ESO Public Surveys releaseshttp://www.astro-wise.org/ : Astro-WISE (Astronomical Wide-field Imaging Systemhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=II/347https://vizier.iucaa.in/viz-bin/VizieR-2?-source=II/347http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=II/347https://vizier.cds.unistra.fr/viz-bin/votable?-source=II/347https://vizier.iucaa.in/viz-bin/votable?-source=II/347http://vizieridia.saao.ac.za/viz-bin/votable?-source=II/347GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table II/347/kids_dr3 (*KiDS-ESO-DR3 multi-band source catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/II/347/kids_dr3?https://vizier.iucaa.in/viz-bin/conesearch/II/347/kids_dr3?http://vizieridia.saao.ac.za/viz-bin/conesearch/II/347/kids_dr3?GETtext/xml+votable180.050000true134.9987390.0012570.005555555555555556Hips catalogue for table II/347/kids_dr3https://hipscat.cds.unistra.fr/HiPSCatService/II/347/kids_dr3ESO4/1032 1365 1621-1622 1642 1685 1706 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 6748-6750 6814 6819 6828 6830 6912-6914 7834 7845-7846 7856-7857 8823 8829 8831 8907 8967 8971 8973-8975 8982 8984-8986 8996-8998 10239 11262-11263 11639 11643 11719 11732-11734 11736-11738 11745-11747 11749 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 16536-16537 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 26028-26029 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 26909 26911 26945-26947 26985-26988 26991 27004-27006 27029 27031 27033-27036 27038 27045-27047 27049-27054 27056-27058 27072-27074 27088-27089 27221-27223 27229 27245 27247 27270-27271 27273-27275 27288 27290-27291 27316 27318-27319 27324-27326 27392-27394 27660-27662 27664-27666 27680-27682 31293-31295 31330-31331 31340 31342-31343 31373 31375 31377-31379 31388-31390 31393-31395 31397-31399 31401-31404 31408-31410 31433 31436-31437 34539-34540 34542-34543 35287 35291 35313-35315 35320-35321 35323 35627 35665 35668-35669 35716 35863 35867 35879 35889-35891 35922-35923 35948 35952 36000-36002 36008 36010 36016 36032 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 47008-47009 47011-470142.381800341673347e-19 6.090060298487514e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/II/347?format=asciiOpticalInfrareddefaultII/347/kids_dr3*KiDS-ESO-DR3 multi-band source cataloge_imagISO[0/100]?
