cds-question@unistra.frgalaxiescatalogshst-photometrygalaxy-classification-systemsWe present a catalogue of photometric and structural properties of 228 nuclear star clusters (NSCs) in nearby late-type disc galaxies. These new measurements are derived from a homogeneous analysis of all suitable Wide Field Planetary Camera 2 (WFPC2) images in the Hubble Space Telescope (HST) archive. The luminosity and size of each NSC are derived from an iterative point spread function (PSF) fitting technique, which adapts the fitting area to the effective radius (r_eff_) of the NSC and uses a WFPC2-specific PSF model tailored to the position of each NSC on the detector. The luminosities of NSCs are <=10^8^L_V,{sun}_, and their integrated optical colours suggest a wide spread in age. We confirm that most NSCs have sizes similar to globular clusters (GCs), but find that the largest and brightest NSCs occupy the regime between ultra-compact dwarf (UCD) and the nuclei of early-type galaxies in the size-luminosity plane. The overlap in size, mass, and colour between the different incarnations of compact stellar systems provides a support for the notion that at least some UCDs and the most massive Galactic GCs may be remnant nuclei of disrupted disc galaxies. We find tentative evidence for the NSCs' r_eff_ to be smaller when measured in bluer filters and discuss possible implications of this result. We also highlight a few examples of complex nuclear morphologies, including double nuclei, extended stellar structures, and nuclear F606W excess from either recent (circum-)nuclear star formation and/or a weak active galactic nucleus. Such examples may serve as case studies for ongoing NSC evolution via the two main suggested mechanisms, namely cluster merging and in situ star formation.2014MNRAS.441.3570Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/441/3570CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/441/3570https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/441/3570http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/441/3570https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/441/3570https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/441/3570http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/441/3570GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/441/3570/catalog (Catalog of Nuclear Star Clusters: main properties of galaxies (table1), radiuses (table3), ellipticities (table4), and photometry (table5))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/441/3570/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/441/3570/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/441/3570/catalog?GETtext/xml+votable180.050000true156.6157567.65697220.005555555555555556Cone search capability for table J/MNRAS/441/3570/table2 (Main properties of the galaxy sample without an identifiable (Nuclear Star Cluster) NSC)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/441/3570/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/441/3570/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/441/3570/table2?GETtext/xml+votable180.050000true111.888-45.68447220.0055555555555555566/816 2121 2155 2324 2372 2380 2383 3389 3438 3483 3506 4178 4181 4405 4511 4989 4991 5061 5142 5174 5342 5545 5586 5589-5590 5607 5623 5634 5715 5797 5966 5978 5980 5995 6007 6047 6124 6399 6619 6623 6649 6772 6948 7110 7303 7485 7498 7577 7582 7584 7602 7618 7649 7658 7726 7946 7997 8113 8225 8359 8458 9109 9437 10240 10490 10739 10755 10761-10762 10769 10787 10809 10841 10881 10900-10901 10905 10910-10911 10935 10955 10977 10986 11127 11246 11375 11434 11448 11460 11582 11639 11772 12122 13510 13522 13672 15594 16098 16441 16470 16519 16595 16701 16871 17493 17592 17598 17606 17759 17780 17905 17927 18011 18041 18398 18429 19678 20270 20353 20526 20605 20720 20875 20929 21026 21064 21198 21216 22427 22751 23113 23887 24437 24735 24777 24912 24949 25079 25135 25144 25173 25205 25344 25438-25439 25599 25762-25763 25785 25889-25890 25960 25966 25997 26068 26128 26148 26214 26217 26222 26234 26260 26265 26268 26303 26317 26338 26353 26388 26472 26803 27030 27458 27504 27568 27603-27604 27606 27653 27724 27731 27736 27741 27763 27770 27823 27828 27855 27858 27860-27861 27863 27918 27926 27941-27943 27949 27955 28033 28035 28037-28038 28053 28077 28126 28294 28299 28486 28496 28508 28529 28535 28612 28631 28637 28666 29718 30970 31469 31795 31880 33077 33137 33193 33228 33242 33337 33646 33650 33656 33832 33920 33951 33957-33958 34051 34328 34334 34352 34403 34493-34494 34511 34538 34638 34641 34692 35536 35863 35908 35924 35929 36134 36151 36172 36234 36236 36276 36756 36785 36789 38390 38486 38655 38841 39127 39156 40210 40234 40328 40363 40722 42025 42923 43246 43318 43325 43361 43397 43420 43662 43706 43845 43878 43881 43935 43948 43956 44000 44003 44203 44582 45367 45732 45748 45914 45928 46170 46417 46460 46467 46491-46492 46519 46525 46549 46568 46597 46689 46808 484842.0401237512456292e-19 7.605786964834612e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/441/3570?format=asciiOpticaldefaultJ/MNRAS/441/3570/catalogCatalog of Nuclear Star Clusters: main properties of galaxies (table1), radiuses (table3), ellipticities (table4), and photometry (table5)S9Shape index at F675W (3)src.morph.paramcharNameGalaxy namemeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
