Left: Histogram of ﹩N_{\mathrm{H}\,}﹩ derived through spectral fits of the 209 brightest cluster members. While the distribution is peaked at ﹩2.8\times 10^{22}﹩ cm−2, at least two cluster members have an order of magnitude more absorption. Right: Histogram of ﹩N_{\mathrm{H}\,}﹩ for the 157 cluster members with <30 counts.
