Temperature as a function of distance from the filament spines. The solid yellow line is the best-fit profile for the high δ_LD sample with its respective distribution indicated by the pink bars (same as in Fig. 13). The black dash-dotted line is the temperature derived by Tanimura et al. (2020) from Planck tSZ and CMB-lensing observations, with the grey area showing the error. The dashed line at log T(K) = 5.5 indicates the lower limit for the hot WHIM.
