Comparison of the dust structures in Zw049 derived from the best-fit E(B − V) value template for the stellar reddening (contours) and the Balmer decrement (image). Contours levels denote E(B − V) = 0.1, 0.2, 0.3, 0.4, 0.5, and 0.6. The black cross denotes the position of the CON source for reference. A 3σ noise cut has been applied to the Balmer decrement map to include only pixels for which both Hα and Hβ lie above this noise threshold. The map has been smoothed with a 1σ Gaussian kernel to improve the visual output.
