Gas, stellar (including ICL), and baryon fraction of clusters within R500 for four cluster mass bins: Bin 1 (
), Bin 2 (
), Bin 3 (
), and Bin 4 (
).
are averages from Chandra and XMM observations (12–15). fstars and the 10% ICL contribution are from (15, 31, 32). The error bars are 1-σ errors on the mean.
