Candidates have been selected from B, V, and I band images taken with the Hubble Space Telescope, which also reveal 17 younger ({tau}<~fewx100Myr) clusters. The luminosity function shows a peaked shape similar to that found for GC systems in other spiral and elliptical galaxies. The ancient clusters have a bimodal color distribution, with approximately 65% (35%) of the population having blue (red) colors. The red, presumably metal-rich, GCs are more centrally concentrated, as expected for a bulge population; while the blue, presumably metal-poor, GCs are more broadly distributed, consistent with expectations of a halo population. The specific frequency of GCs in NGC1291 is higher than found previously in most spiral galaxies. However, if we consider just the blue subpopulation, we find SN,blue=0.50{+/-}0.06, quite similar to that found for other spirals. This result supports the hypothesis of a universal population of halo GCs in spirals. The fraction of red GCs in NGC1291, when compared with those found in other galaxies, suggests that these correlate with host galaxy type rather than with host galaxy luminosity.2022AJ....163..271Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/163/271CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/195 : Globular Clusters in the Milky Way (Harris, 1996)VII/202 : Globular Clusters in the Milky Way (Harris, 1997)J/ApJS/122/431 : Star Clusters in M33 (Chandar+, 1999)J/A+AS/139/393 : Young Massive Star Clusters.
