cds-question@unistra.frsurveysvisible-astronomysloan-photometryThe VLT Survey Telescope ATLAS survey is an optical ugriz survey aiming to cover ~4700deg^2^ of the southern sky to similar depths as the Sloan Digital Sky Survey (SDSS). From reduced images and object catalogues provided by the Cambridge Astronomical Surveys Unit, we first find that the median seeing ranges from 0.8-arcsec FWHM (full width at half-maximum) in i to 1.0-arcsec in u, significantly better than the 1.2-1.5arcsec seeing for SDSS. The 5{sigma} mag limit for stellar sources is r_AB_=22.7 and in all bands these limits are at least as faint as SDSS. SDSS and ATLAS are more equivalent for galaxy photometry except in the z band where ATLAS has significantly higher throughput. We have improved the original ESO magnitude zero-points by comparing m<16 star magnitudes with the AAVSO Photometric All-Sky Survey in gri, also extrapolating into u and z, resulting in zero-points accurate to ~+/-0.02mag. We finally compare star and galaxy number counts in a 250deg^2^ area with SDSS and other count data and find good agreement. ATLAS data products can be retrieved from the ESO Science Archive, while support for survey science analyses is provided by the OmegaCAM Science Archive, operated by the Wide-Field Astronomy Unit in Edinburgh.2015MNRAS.451.4238Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/II/350CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=II/350https://vizier.iucaa.in/viz-bin/VizieR-2?-source=II/350http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=II/350https://vizier.cds.unistra.fr/viz-bin/votable?-source=II/350https://vizier.iucaa.in/viz-bin/votable?-source=II/350http://vizieridia.saao.ac.za/viz-bin/votable?-source=II/350GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table II/350/vstatlas (VST ATLAS DR3 catalog, output (106,775,847 sources))https://vizier.cds.unistra.fr/viz-bin/conesearch/II/350/vstatlas?https://vizier.iucaa.in/viz-bin/conesearch/II/350/vstatlas?http://vizieridia.saao.ac.za/viz-bin/conesearch/II/350/vstatlas?GETtext/xml+votable180.050000true1.193803-39.9942580.005555555555555556Hips catalogue for table II/350/vstatlashttps://hipscat.cds.unistra.fr/HiPSCatService/II/350/vstatlasESO2/65-66 142 3/257-259 268 272 288 395-398 401-402 416-417 557-559 561-564 566-567 572 700 702 733-735 757 4/1025-1027 1076 1080 1092 1096 1156 1160 1565-1567 1575 1579 1596-1598 1601-1603 1612-1614 1616-1618 1632-1634 1672-1673 1675-1678 1680-1682 2157-2159 2205-2207 2221-2223 2225-2227 2241-2243 2292 2296 2519 2779 2797-2799 2804 2806-2807 2812-2814 2909-2911 2925 2927 2929-2931 3024-3025 3027 3036-3037 3039 5/4097-4099 4308-4310 4312-4314 4324-4326 4328-4330 4372-4374 4376-4378 4388-4390 4392-4394 4628-4630 4632-4634 4644-4646 4648-4650 5666 5672-5674 6229-6231 6233-6236 6239 6245-6247 6249-6252 6254-6256 6259 6293-6295 6297-6299 6309-6311 6313-6315 6396-6398 6400 6403 6460-6462 6476-6478 6480-6482 6496-6498 6540-6542 6544-6546 6560-6562 6697 6716-6718 6732-6734 6736-6738 6752-6754 6789 6800-6802 7818 7840-7842 8606 8621-8623 8625-8627 8674 8680 8682-8683 8686 8797-8799 8813-8815 8817-8819 8861-8863 8877-8879 8881-8883 8897-8899 8961-8963 9042 9048 9050-9051 9054 9172-9174 9176-9178 9188-9190 9192-9194 10069-10071 10073 10101 11110 11113-11115 11130 11157-11159 11163-11165 11167 11175 11179-11180 11183-11184 11187 11222 11260-11262 11613-11615 11629-11631 11633-11635 11677-11679 11697-11699 11704-11705 11707 11713-11715 12052-12053 12055 12104-12105 12107 12132-12133 12135 12152-12153 12155 12244-12245 6/16385-16387 17244 17260 17264 17308 17324 17328 17344 17500 17516 17520 17564 17580 17584 17600 17664 17920 18524 18540 18544 18588 18604 18608 18624 18688 18944 22658 22700 23040 24831 24895 24911 24915 24931 24948 24951-24952 24955 24975 24979 24995 25012 25015 25028 25031-25032 25035 25151 25167 25171 25187 25231 25235 25251 25596 25604 25607-25608 25611 25852 25916 25932 25936 25952 25996 26000 26016 26172 26188 26192 26208 26252 26256 26272 26785 26797 26876 26940 26956 26960 26976 27020 27024 27040 27153 27165 27212 27216 31264 31266-31267 31276 31278-31279 31372 31392 34413-34415 34430 34461-34463 34477-34479 34481-34483 34497-34499 34690 34702 34724 34726-34727 34738 34750 35165-35167 35181-35183 35185-35187 35229-35231 35245-35247 35249-35251 35265-35267 35421-35423 35437-35439 35441-35443 35485-35487 35501-35503 35505-35507 35521-35523 35585-35587 35841-35843 36162 36174 36196 36198-36199 36210 36700 36716 36720 36764 36780 36784 36800 38911 40271 40275 40301 40401 40413 44031 44287 44431 44435 44444 44446-44447 44451 44512 44514-44515 44524 44526 44627 44645-44647 44649-44651 44664 44667 44693-44695 44697-44699 44709-44711 44713-44715 44724 44727-44728 44731 44740 44743-44744 44747 44880 44882-44883 44894-44895 45052 46429-46431 46445-46447 46449-46451 46493-46495 46509-46511 46513-46515 46529-46531 46685-46687 46701-46703 46705-46707 46749-46751 46772-46773 46775 46785-46787 46824-46825 46827 46849-46851 48196-48197 48199 48216-48217 48219 48244-48245 48247 48424-48425 48427 48516-48517 48519 48536-48537 48539 48564-48565 48567 48616-48617 48619 48964-48965 48967 48984-48985 48987-489882.1405905346066806e-19 2.393642124494231e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/II/350?format=asciiOpticaldefaultII/350/vstatlasVST ATLAS DR3 catalog, output (106,775,847 sources)R-Iext?
