Resulting diagrams for the GoMar23 model when the following parameters vary (from left to right): the viewing angle, the half opening angle, the ratio between the outer and the inner radius, the optical extinction at the equator, and the radial distribution of the dust. From top to bottom: α_{5.5 − 7.5 μm} versus α_{7.5 − 14 μm}, α_{25 − 30 μm} versus α_{7.5 − 14 μm}, and S_10 μm versus α_{5.5 − 7.5 μm}. The gray contour shows the result for the entire SED library. The blue, purple, and pink areas show the locus of SEDs for the minimum, medium, and maximum values of the parameter, respectively (see legend in the top panels). The results for the maximum grain size are shown in Fig. 5. We skip the results for the polar density distribution of the dust since no differences are found.
