Notes.

^(a)

Component.

^(b)

Independent parameter.

^(c)

Column density of H₂, calculated assuming a mass-absorption coefficient of 44.4 cm² g^-1 at 100 μm and a gas-to-dust mass ratio of 100.

^(d)

Estimated gas mass, assuming spherical symmetry.

^(e)

Unattenuated dust luminosity of the component.
