Relative distribution of neutral hydrogen and OB associations. The grey shadow outlines the distribution of HI in IC 1613 (adapted from Fig. 1 of Silich et al. 2006). Colored contours indicate the position of the associations of Garcia et al. (2009). Color indicates the age of the youngest members, with the same color code as in Fig. 10. Numbers follow the HI fragment numbering of Silich et al. (2006). The HI cavity is surrounded by fragments 1, 10, 11, 14, and 17.
