Impact of the hydrostatic bias b on the integrated quantities, represented as the ratio between the quantities estimated for an assigned bias, and with bias equal to zero. From left to right: this ratio for total mass, temperature, gas mass, core-excised bolometric luminosity, and f_T = T(R₅₀₀)/T_spec. Shown is the case of a system with M₅₀₀ = 5 × 10¹⁴ M_⊙ at z = 0.05 and 0.5 (the values at different redshifts overlap for most of the quantities).
