cds-question@unistra.frgalaxiesvisible-astronomycatalogsA full ring is a form of galaxy morphology that is not associated with a specific stage on the Hubble sequence. Digital sky surveys can collect many millions of galaxy images, and therefore even rare forms of galaxies are expected to be present in relatively large numbers in image data bases created by digital sky surveys. Sloan Digital Sky Survey (SDSS) data release (DR) 14 contains ~2.6x10^6^ objects with spectra identified as galaxies. The method described in this paper applied automatic detection to identify a set of 443 ring galaxy candidates, 104 of them were already included in the Buta (2017MNRAS.471.4027B, Cat. J/MNRAS/471/4027) catalogue of ring galaxies in SDSS, but the majority of the galaxies are not included in previous catalogues. Machine analysis cannot yet match the superior pattern recognition abilities of the human brain, and even a small false positive rate makes automatic analysis impractical when scanning through millions of galaxies. Reducing the false positive rate also increases the true negative rate, and therefore the catalogue of ring galaxy candidates is not exhaustive. However, due to its clear advantage in speed, it can provide a large collection of galaxies that can be used for follow-up observations of objects with ring morphology.2020MNRAS.491.3767Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/491/3767CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/471/4027 : CVRHS classifications for the GZ2 Ring Sample (Buta, 2017)J/ApJS/223/20 : SDSS-DR8 galaxies classified by WND-CHARM (Kuminski+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/491/3767https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/491/3767http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/491/3767https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/491/3767https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/491/3767http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/491/3767GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/491/3767/table1 (Ring galaxy candidates identified automatically)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/491/3767/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/491/3767/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/491/3767/table1?GETtext/xml+votable180.050000true249.47845.6950.0055555555555555566/4152 4176 4178 4183 4191 4255 4268 4276 4281-4282 4348 4422 4489 4516 4589 4595 4614 4641 4657 4670 4697 4705 4745 4794 4801 4844 4880 4916 4933 4953 5003 5050 5106 5149 5161 5196 5203 5220 5225 5243 5348 5363 5373 5439 5485 5487 5492 5501 5530-5531 5555 5558 5591 5594 5643 5664 5792 5801 5837 5839-5840 5852 5866 5881 5900 5919-5920 5940 5960 5963 5977 5980-5981 5989 6021 6039 6051 6084 6106 6208 6226-6227 6266 6341 6449 6485 6519 6547 6580 6585 6603 6625 6933 7180 7184 7223 7245 7254 7277 7280 7300 7312 7334 7395 7426 7448 8215 8221 8223 8256 8265 8299 8331 8388 8421 8457 8460 8462 8464 8492 8505 8520 8525 8557 8593 8604 8613 8632 8643 8651 8661 8675 8692 8700 8741 8750 8812 8835 8859 8867 8869 8892 8924 8940 8961 8965 8970 8980 8992 8999 9031 9037-9038 9084 9091 9118 9163 9213 9219 9224 9229 9247 9332 9336 9350 9380 9392 9400 9452 9465 9469 9471 9484 9512 9729 9747 9781 9783 9795 9804 9821 9828 9841 9848 9881 9883 9917 9931 9958 9996 10155 10267 10270 10324 10328 10349 10358 10396 10416-10418 10423 10429 10433 10435 10439 10448 10452 10494 10498 10540-10541 10550 10608 10653 10686 10691 10707 10772 10776 10810 10830 10850 10880 10907 10914 10944 10948 11005 11048 11058 11084 11106 11141 11143 11162 11175 11178 11182 11185 11292 11314 11369 11409 11427 11435 11437 11464 11591 11602 11792 11808 11819 11854 11908 11942 11948-11949 12391 12405 12551 17252 17508 17559 17579 17664 17815-17816 17835 17981 18006 18084 18176 18302 18405 18407 18618 18624 18687 18750 18775 18795 18840 18844 18846 18858 18926 18948 18950 18953 19056 19085 19092 19100 19324-19325 19379 19424 19684 19764 19994 20010-20011 21971 22006 22361 22367 22388-22389 23055 23146 23205 23207 23210 25598 25844 25847 25849 25929 25932 25936 25939 25952-25953 25965 25991 26001-26002 26065 26070 26073 26080 26083 26097 26110 26157 26172 26201 26207 26223 26266 26280 26306 26351 26486 26513 26520 26532 26561 26570 26584 26586 26959 26975 26977 27000 27064 27074 27082 27089 27117 27125 27215 27219 27247 27333 27347 27417 27443 27493 27524 27535 27553 27573 27579 27583 27635 27658 27780-27781 27812 27816-27817 27824 27855 27888 27901 27960 27999 28004 28020-28021 28058 28065 28071 28100 28187 28206 28214 28216 28218 28230 28241 28243 28251 28266 28278 28294 28333 28348 28381 28392 28405 28408 28461 28495 28560 28611 28669 30039 30065 31415 31426-31427 31620 31625 31694 31717 32429 32491 36785 49128 49150https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/491/3767?format=asciiOpticaldefaultJ/MNRAS/491/3767/table1Ring galaxy candidates identified automaticallyID[1/443] Internal object identifiermeta.id;meta.mainintprimaryrecnoRecord number assigned by the VizieR team.
