cds-question@unistra.frgalaxiesphotometryinfrared-photometrysurveysWe present the deepest Spitzer/InfraRed Array Camera (IRAC) 3.6, 4.5, 5.8, and 8.0{mu}m wide-area mosaics yet over the Great Observatories Origins Deep Survey (GOODS)-N and GOODS-S fields as part of the GOODS Reionization Era wide-Area Treasury from Spitzer (GREATS) project. We reduced and mosaicked in a self-consistent way observations taken by the 11 different Spitzer/IRAC programs over the two GOODS fields from 12yr of Spitzer cryogenic and warm- mission data. The cumulative depth in the 3.6{mu}m and 4.5{mu}m bands amounts to ~4260hr, ~1220hr of which are new very deep observations from the GREATS program itself. In the deepest area, the full-depth mosaics reach >~200hr over an area of ~100arcmin^2^, corresponding to a sensitivity of ~29 AB magnitude at 3.6{mu}m (1{sigma} for point sources). Archival cryogenic 5.8{mu}m and 8.0{mu}m band data (a cumulative 976hr) are also included in the release. The mosaics are projected onto the tangential plane of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey/GOODS at a 0.3/pixel scale. This paper describes the methodology enabling, and the characteristics of, the public release of the mosaic science images, the corresponding coverage maps in the four IRAC bands, and the empirical point-spread functions (PSFs). These PSFs enable mitigation of the source blending effects by taking into account the complex position-dependent variation in the IRAC images. The GREATS data products are in the Infrared Science Archive. We also release the deblended 3.6-8.0{mu}m photometry 9192 Lyman-break galaxies at z~3.5-10. GREATS will be the deepest mid-infrared imaging until the James Webb Space Telescope and, as such, constitutes a major resource for characterizing early galaxy assembly.2021ApJS..257...68Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/257/68CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/261 : GOODS initial results (Giavalisco+, 2004)I/345 : Gaia DR2 (Gaia Collaboration, 2018)I/353 : The Guide Star Catalog, Version 2.4.2 (GSC2.4.2) (STScI, 2020)J/AJ/120/2747 : HDF-South WFPC2 observations (Casertano+, 2000)J/A+A/379/740 : ESO Imaging Survey (EIS) (Arnouts+, 2001)J/ApJS/177/431 : Mid-IR sources in EGS (Barmby+, 2008)J/ApJS/188/178 : VLA 1.4GHz observations of GOODS-North field (Morrison+, 2010)J/ApJS/187/251 : Ultradeep Ks imaging in the GOODS-N (Wang+, 2010)J/ApJ/727/1 : IRAC/MUSYC SIMPLE survey (Damen+, 2011)J/PASJ/63/S379 : MOIRCS Deep Survey deep and wide catalogs (Kajisawa+, 2011)J/ApJ/754/83 : UV continuum for z~4-7 star-forming galaxies (Bouwens+, 2012)J/ApJ/769/80 : Spitzer/IRAC observations of five deep fields (Ashby+, 2013)J/A+A/570/A11 : The Hawk-I UDS and GOODS Survey (HUGS) (Fontana+, 2014)J/ApJS/214/24 : 3D-HST+CANDELS catalog (Skelton+, 2014)J/ApJS/218/33 : Spitzer-CANDELS catalog within 5 deep fields (Ashby+, 2015)J/ApJ/803/34 : z~4-10 galaxies from HST legacy fields (Bouwens+, 2015)J/ApJ/810/71 : UV mag of candidate galaxies at 3~<z~<8.5 (Finkelstein+, 2015)J/ApJS/221/23 : IRAC HUDF and GOODS ultradeep surveys (Labbe+, 2015)J/ApJS/219/15 : Morphologies of z=0-10 galaxies with HST data (Shibuya+, 2015)J/ApJS/237/39 : Spitzer survey of UltraVISTA deep Stripes (Ashby+, 2018)J/A+A/618/A85 : Spectroscopy of 3<z<4 quiescent galaxies (Schreiber+ 2018)J/ApJS/244/16 : HLF photometric catalog in GOODS-S v2.0 (Whitaker+, 2019)J/A+A/634/A97 : VUDS UV and Ly{alpha} luminosity functions (Khusanova+, 2020)J/ApJ/889/189 : Brightest high-z galaxies in RELICS clusters (Salmon+, 2020)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/257/68https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/257/68http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/257/68https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/257/68https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/257/68http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/257/68GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/257/68/table3 (GREATS photometry for the Lyman-break galaxies of Bouwens+ (2015, J/ApJ/803/34))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/257/68/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/257/68/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/257/68/table3?GETtext/xml+votable180.050000true189.4522041762.237730560.005555555555555556Cone search capability for table J/ApJS/257/68/table2 (Summary of GOODS Reionization Era wide-Area Treasury from Spitzer (GREATS) AORs)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/257/68/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/257/68/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/257/68/table2?GETtext/xml+votable180.050000true189.26132262.18383410.0055555555555555566/11252 359352.0616683193919197e-20 6.185923063528282e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/257/68?format=asciiInfrareddefaultJ/ApJS/257/68/table3GREATS photometry for the Lyman-break galaxies of Bouwens+ (2015, J/ApJ/803/34)recnoRecord number assigned by the VizieR team.
