Notes.

(1)

ID is the identifier used in the model. These identifiers follow the historic naming scheme explained in Sect. 1.

(2)

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

(3)

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

(4)

Dec is the declination. Both coordinates are given in units of degrees:arcminutes:arcseconds in the equatorial system.

(5)

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.

(6)

rx, ry, rz are the core radii in each principal direction, as described in Eq. (4).

(7)

nc is the central density.

(8)

η is the exponent of the dust density profile.

(9)

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.
