Density profile on the first row and temperature profile on the second, for the DiskFit best models. The 1st column is for dust, the 2nd for ¹³CO, the 3rd for ¹²CO (2-1) and (3-2) and the 4th for HCO⁺. The solid vertical line represents the beam, and the curved horizontal lines correspond to one and two scale heights. Note: the density profile scale (in cm⁻³) is expressed in log₁₀. The densities shown for the molecular tracers correspond to the number density of the specific molecule, not the total H2 density, and are therefore several orders of magnitude lower than dust-derived gas densities.
