Notes.

(a)

Size of the Spitzer/IRAC 3.6 μm stellar disk convolved with the beam of SPIRE 250 μm.

(b)

Size of the dusty disk at 250 μm.

(c)

Total flux is the sum of the measured fluxes of the stellar disk, plus the diffuse emission.

(d)

Dust mass deficiency as described in Sect. 3.1

(e)

Fraction of the dust deficit (MD,def/[Mdust + MD,def]).

(f)

The diffuse dust masses were estimated using Eq. (1) at 250 μm, for β = 1.5 and T ranging between 15 and 20 K.

(g)

Galaxies with dust disk reduced in comparison with the stellar one.

(h)

The diffuse dust flux density can be different for HCG92b and HCG92c depending on where we assign the dusty filament.

(†)

Galaxy HCG56b is flagged because it host a powerful AGN which dominates its mid-IR colours.
