Derived averaged radial linewidth and virial parameter profiles. The dash-dotted line in each upper panel indicates the power-law fit to the linewidths from the thermometer lines. In each upper panel the gray dotted line indicates the relation found by Caselli & Myers (1995) of Orion low-mass cores scaled up by a factor of 5, which roughly matches the observed linewidth in our case, of . The gray dashed line shows a relation of Δv∕1 km s⁻¹ = 6.0 (r∕1 pc)^0.2. These two reference lines are identical in all plots. In each lower panel, the ratio of α_vir to the critical virial parameter α_cr is shown; the horizontal solid and dotted line indicate a ratio of 1 (equipartition) and 0.5 (virial equilibrium), respectively. All plots except for G10 and G18 share the same legend shown in the middle panel of the last row, where the color-coding for the thermometer lines is the same as in Fig. 20.
