All Tables

Table 1: Apparent gas mass fractions at ${r_{\rm 500}}$ in both EdS and $\Lambda$ CDM cosmologies with h = 0.5, uncorrected for clumping, with uncertainties from temperature uncertainties. Temperature measurements are taken from Lumb et al. (2004) without cooling flow excision.
Table 2: Least square fit of the gas fraction versus temperature T (in keV) to the local sample of X-ray clusters. Uncertainty in the normalization constant is 4-5%. The dispersion around the fit is also given in percentage.
