Intensity raster map with averaged spectral intensity represented in log-scale. Gray dashed lines delimit the region containing the planetary limb. These represent two concentric ellipses centered at (X, Y) = (57″, 39.75″), marked with a red cross. Two vertical dashed lines were included to outline the region of the limb where the atmospheric aureole is observed. Two solid gray lines delimit the location of the solar limb. -- MDPI
