Fig. 10.

Isochrones of 105.3 yr ≃ 2 × 105 yr and 105.7 yr ≃ 5 × 105 yr for the two scenarios described in Sect. 4.2. Isochrones of scenario 1 are plotted with solid lines, while those of scenario 2 are shown by series of squares (105.3 yr) and triangles (105.7 yr). The colours of the lines and squares indicate the age.
