Notes.

^(a)

Dust velocities in the size range a_min–a_max (a_min = 0.1 μm);

^(b)

upper limit (5-σ) on the dust production rate from 70-μm PACS data;

^(c)

the lower and higher values correspond to carbon and olivine grains, respectively;

^(d)

upper limit (5-σ) on the dust production rate from 100 μm PACS data.
