Results obtained for the eight cloud configurations described in Table 3. Left: spatially-averaged spectra of the 353 GHz dust intensity of the n_cl clouds, ℂ_i (i = 1, …, n_cl), all in the same (arbitrary) units. Center: maps of the 353 GHz dust intensity (in MJy sr⁻¹) of the n_cl clouds. The polarization fractions, ${\overline{p}}_{\text{d},i}$, and polarization angles, ${\overline{\psi }}_{\text{d},i}$, of the clouds are indicated by the length and orientation of the overplotted white headless vectors. To help make the connection between spectra and maps, each map is topped with a thick band having the same color as the associated spectrum. Right: maps of the resulting polarized intensity, $p_{\text{d}}^{\mathrm{mod}}$, LoS-averaged polarization fraction, $p_{\text{d}}^{los,\mathrm{mod}}$, and LoS-averaged polarization angle, ${\psi }_{\text{d}}^{los,\mathrm{mod}}$, all in the same units as in Fig. 9. For reference, the corresponding observational Planck maps are shown in the top row.
