Top row: reconstructed image (left) and synthetic intensity maps computed for the best matching RHD simulations of Table 3 at 4.57 μm. The intensity is normalised between [0, 1]. The images, 256 × 256 pixels with 0.39 mas pixel⁻¹, were convolved with the interferometric beam (Fig. 1). The contour lines are the same as in Fig. 4. East is left, while north is up. Bottom row: synthetic intensity maps from the above snapshots non-convolved with the interferometric beam. The peak intensity is normalised between [0, 1]. The RSG snapshot , while the AGB one is .
