... Until recently, the only known exception to this rule was the cluster OmegaCentauri, which is significantly more massive than most clusters and has both double main sequence and a range of metallicities among the evolved stars. ...
... In Cycles 18, 19, 20, the globular cluster OmegaCentauri was observed through 14 UVIS and 5 IR filters (WFC3 Calibration Programs 11911, 11928, 12353 and 13100). ...
... Up until about 5 years ago, the only known counter-example to convention was the cluster OmegaCentauri, which is significantly more massive than most clusters and has both a complex main sequence structure and a range of metallicities among the evolved ...

... The paper compares WFPC2 observations with ground based observations of OmegaCentauri and NGC 2419, using a baseline through March 2000, roughly a year longer than available for a similar study by Whitmore, Heyer, and Casertano (1999, PASP, 111, 1559). ...

... specifically, the two nearest clusters, NGC 6397, an extremely metal-poor cluster, and M4, a moderately metal-rich systems; OmegaCentauri, one of the most massive clusters, perhaps even the remnant core of a dwarf galaxy; and 47 Tucanae, one of the ...
