QuACK-map of 67P’s nucleus, centered on its south pole (SP). The colored shapes show how the ellipses that mark the suspected source regions project onto the surface. The lines in the respective colors indicate the projected ellipse centers. For the geographic data such as surface regions (black lines), latitudes (dotted, light gray lines), and longitudes (dashed, gray lines), the publicly available maps provided by Leon-Dasi et al. (2021)³ were used (slightly modified). For the data of the bright spots, see also Oklay et al. (2017); Deshapriya et al. (2018); Hasselmann et al. (2019); Fornasier et al. (2016, 2017).
