Notes. The value of the reduced χ2 is given in Col. 2, the intensity of the RF in Col. 3, the abundances of the different dust components in Cols. 4–7, the total dust abundance in Col. 8, the intensity of the NIR continuum in Col. 9, the small-grain size parameters in Cols. 10–12 (with amin and amax in nm), and the ratio of the a-C component abundance over the total large-grain abundance in Col. 13. Bottom table: Same as the top table, but using a 4 Myr RF. A null abundance is not possible for computational reasons and is set to 1.00 × 106 instead. Standard parameters for our Galaxy are also given for comparison.
