Notes.

(1)

MAC averaged over the four unprocessed samples E10, E20, E30, E40.

(2)

MAC averaged over the four processed samples E10R, E20R, E30R, E40R.

(3)

MAC averaged over the eight samples E10, E20, E30, E40 and E10R, E20R, E30R, E40R.

(4)

These MAC are calculated using the optical constants of the “astrosilicates” from Li & Draine (2001; Sect. 4.3).
