Maps and deprojected properties of the extinction in the host, derived from different measurements. Top panels: E(B − V) determined from the Balmer decrement after correcting Hα and Hβ for stellar absorption. Bottom left panel: Extinction map using the correlation between the NaD EW and extinction from Poznanski et al. (2012). Bottom right panel: Extinction map from the stellar population fitting. The maps at the bottom were obtained from the Voronoi binned cube; the white region is a bin affected by a foreground star and has been omitted. Overplotted contours are derived from the ALMA CO(1−0) map (see de Ugarte Postigo et al. 2024).
