The extinction factors of CO ice stretching mode for four of the aggregates shown in Fig. 3 with X values of 0.5 (upper left), 1 (upper right), 1.5 (bottom left) and 2 (bottom right) and monomer radius of 0.1 μm, including a 25% of the silicate (dotted line) compared with the results previously obtained for these aggregates without silicate (solid line).
