This dataset will allow for the construction of the most complete catalogue of stellar clusters obtained for a spiral galaxy. Here, we provide an overview of the PHAT survey, a progress report on the status of observations and analysis, and preliminary results from the PHAT cluster program. Although only ÃÅ 20% of the survey is complete, the superior resolution of HST has allowed us to identify hundreds of new intermediate and low-mass clusters. As a result, the size of the cluster sample within the Year 1 survey footprint has grown by a factor of three relative to previous catalogues. | | Comment of the Author/Creator: | Date: 2011 online, n/a 1, 2011 | | External Publication Status: | published | | Document Type: | Conference-Paper |
