Derived polarization (PI) and total intensities (I) from the two-component model introduced in Sect. 4.1 (Eq. (1)), with α = 10% (Eq. (4)), and observing frequency ν = 44 GHz. Color bars are in mJy beam⁻¹ units. Horizontal and vertical axes are dust temperatures of the background and foreground components T_fg and T_bg. White dashed lines show T_fg = T_bg. From top to bottom, the rows show the cases of τ = 0.1, 1, and 3, respectively.
