cds-question@unistra.frgalaxiesstellar-associationshst-photometryWe have used deep ACS/WFC images of M33 to check the nature of extended objects detected by the ground based survey of Zloczewski et al. (2008, Cat. J/AcA/58/23). A total of 24 candidates turned out to be genuine compact stellar clusters. In addition we detected 91 new clusters. Equatorial coordinates, integrated magnitudes and angular sizes are listed for all 115 objects. Forty-two clusters have sufficiently red colors to be candidates for old globulars. For four clusters we extracted resolved stellar photometry. Object 33-3-018 located in the outer disk of M33 turned out to be a young cluster with an age estimated at 200-350Myr. Cluster ZK-90 has an age of 3-5Gyr. The remaining two clusters have intermediate ages ranging from one to a few Gyr.2009AcA....59...47Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AcA/59/47CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AcA/58/23 : Photometric survey for M33 stellar clusters (Zloczewski+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AcA/59/47https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AcA/59/47http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AcA/59/47https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AcA/59/47https://vizier.iucaa.in/viz-bin/votable?-source=J/AcA/59/47http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AcA/59/47GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AcA/59/47/table1 (New classification of 95 objects from the ZKH (Cat.
