ID is the identifier used in the model. These identifiers are identical to the ones introduced by Qin et al. (2011). Note: some of these objects identified by Qin et al. (2011) show an elongated intensity structure. We recover these objects with a superposition of several spherical symmetric clumps. We distinguish these components by adding additional lowercase letters to the identifier introduced by Qin et al. (2011).

Model refers to one of the four model described in this paper.

RA is the right ascension of the density component given in units of hours:minutes:seconds in the equatorial coordinate system.

Dec is the declination of the density component given in units of degrees:arcminutes:arcseconds in the equatorial coordinate system.

dz is the displacement along the line of sight with respect to the model center. The z-axis is oriented such that it points towards the observer.

r₀ is the radius defining the component, as described in Eq. (4).

n_c is the central density.

η is the exponent of the dust density profile.

This column indicates whether an additional heating source had to be included inside the dust component. If this is the case, the spectral type of the star is given.
