Extended Data Figure 3 : Simulation versus data, including first- and second-generation stars.

From: Rapidly rotating second-generation progenitors for the ‘blue hook’ stars of ω Centauri

Extended Data Figure 3

As in Fig. 1 and Extended Data Fig. 1, but the ultraviolet data are compared with a simulation assuming that 50% of blue hook stars are the progeny of the Y = 0.37 population (squares), and 50% are progeny of the Y = 0.25 population (triangles). The error bars are the result of individual 1σ Poisson error on the stellar counts.
