Examples of SED fits of SMC (top row), Galactic (middle), and NGC 6822 (bottom row) RSGs. The orange diamonds show the observations and the black line is the best-fit model consisting of the attenuated flux (dashed light blue), the scattered flux (dash-dotted grey), and dust emission (dotted brown). The top left corner includes the co-ordinates of each source in degrees. Notes: All SED fit figures are available in an electronic form via https://zenodo.org/records/16736627.
