Table 2.
Descriptions and definitions of the parameters used in our model.
| Quantity | Description | Definition |
|---|---|---|
| (1 − b) = h0 | Hydrostatic bias | (1 − b) = MHE/Mtot (see Eq. (A.1)) |
| fT = t0𝒯t1 | Gas temperature at R500 normalised to the global Tspec | fT = T(R500)/Tspec |
| fg = f0𝒯f1 | X-ray-measured gas mass fraction | fg = Mg/MHE |
| fnc = fnc, 0𝒯fnc, 1 | Clumping-corrected gas fraction | fg = C0.5 fnc (see Eq. (14)) |
| C = C0𝒯C1 | Clumping factor | C0.5 = fg/fnc |
| fgas = C−0.5 Mg/Mtot | True (unbiased) gas mass fraction | fgas = (1 − b) fg = (1 − b) C0.5 fnc |
Notes. We define 𝒯 ≡ kBTspec/5 keV.
