Gas, stellar (including ICL), and baryon fraction of clusters within R500 for four cluster mass bins: Bin 1 (Inline graphic), Bin 2 (Inline graphic), Bin 3 (Inline graphic), and Bin 4 (Inline graphic). Inline graphic are averages from Chandra and XMM observations (1215). fstars and the 10% ICL contribution are from (15, 31, 32). The error bars are 1-σ errors on the mean.
