Radial temperature and density profiles of target clumps. Left panel: radial temperature profiles T(r) for all the target sources (Eq. (3), refined T(r) is used for the relevant source). The thickness of the lines increases with increasing luminosity. Right panel: radial (projected radial averaged) density profile of the dense gas (ρ_dense) of all the target sources, from n(H₂) maps derived by RADEX modeling of CH₃OH lines. The range of the y-axis is trimmed to increase contrast. For both panels the luminosity and clump mass are calculated from RADMC-3D best-fit model (Table 6), which takes into account all the gas components present in the clumps.
