Stellar mass within R₅₀₀ as a function of the gas mass (top panel) and total mass (bottom panel) within R₅₀₀ for the X-COP sample (black circles). Black lines are the best fits and shaded areas indicate the 1σ confidence regions, including intrinsic scatters. Top panel: we plot for comparison data from Chiu et al. (2018) (blue circles) and Lin et al. (2012) (yellow circles) samples. Low redshift clusters of both samples are marked with open circles. Bottom panel: we report data by Shan et al. (2015) (green circles). We omit error bars for these samples to avoid overcrowding the plot: typical error bars are shown in the legend. Red lines in the bottom panel represent two fixed levels (0.4% and 1%) of stellar fraction.
