Effect of the dust within the ejecta as viewed from different inclinations. First column: unabsorbed line profile (top) and its absorbed version (bottom) for a biconical ejecta viewed at an inclination, i, of 20°. Middle and right columns: as the left column but for inclination i = 45° and 80°. The adopted ejecta geometry in all cases is that of bicone having opening angle θ/2 = 60° and thickness Δr/R = 0.6. The dust is assumed to be in the inner half of each cone.
