Differences between the predicted and observed gas density and temperature profiles using the datasets from S18 (four panels on the left) and G19a (four panels on the right). Top panels: deviations in terms of σ = (O − M)/ϵ, where O is the observed profile with error ϵ_O and M is the predicted value with an estimated uncertainty of ϵ_M (see Fig. 3) that combines in quadrature with ϵ_O to produce the total error ϵ. Bottom panels: systematic deviation δ = (O − M)/M. Grey lines represent the single object; solid, dashed, and dotted lines indicate mean, median, and scatter, respectively. In the four panels on the left, blue and red lines correspond to the properties of the subsamples at z < 0.6 and z > 0.6, respectively.
