cds-question@unistra.fropen-star-clustersgalaxieshst-photometryultraviolet-astronomyvisible-astronomyinfrared-astronomyastronomical-object-identificationextinctionWe construct a catalog of star clusters from Hubble Space Telescope images of the inner disk of the Triangulum Galaxy (M33) using image classifications collected by the Local Group Cluster Search (LGCS), a citizen science project hosted on the Zooniverse platform. We identify 1214 star clusters within the Hubble Space Telescope imaging footprint of the Panchromatic Hubble Andromeda Treasury: Triangulum Extended Region (PHATTER) survey. Comparing this catalog to existing compilations in the literature, 68% of the clusters are newly identified. The final catalog includes multiband aperture photometry and fits for cluster properties via integrated light spectral energy distribution fitting. The cluster catalog's 50% completeness limit is ~1500M_{sun}_ at an age of 100Myr, as derived from comprehensive synthetic cluster tests.2022ApJ...938...81Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/938/81CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AcA/48/455 : Globular Clusters in M31 and M33 (Mochejska+, 1998)J/ApJS/122/431 : Star Clusters in M33 (Chandar+, 1999)J/A+AS/141/371 : Low-mass stars evolutionary tracks (Girardi+, 2000)J/A+A/366/498 : VI photometry of M33 star clusters (Chandar+, 2001)J/ApJ/614/167 : Planetary nebulae in M33 (Ciardullo+, 2004)J/A+A/444/831 : New star clusters in M33 (Bedin+, 2005)J/AJ/131/2478 : M31 and M33 UBVRI photometry (Massey+, 2006)J/AJ/134/2168 : BVI photometry of M33 star clusters (Park+, 2007)J/AJ/134/447 : Star cluster candidates in M 33 (Sarajedini+, 2007)J/AJ/136/2782 : Star formation efficiency in nearby galaxies (Leroy+, 2008)J/ApJ/699/839 : Identified star clusters in M33.
