Composited SEDs of Hen 2-73 and Hen 2-96 from 100 nm to 1 m. SDSS u′, g′, r′, i′, and t′ data are represented as open squares, DENIS results as filled triangles, the 2MASS measurements as open triangles, WISE photometry as open diamonds, IRAS results as filled circles, MSX photometric measurements as open rhombuses, AKARI results as asterisks, Herschel detections as filled diamonds, and available radio results as filled rhombuses. Note that the IRAS measurements at 100 µm are upper limits and light asterisks represent the uncertain AKARI detections. The dust emissions estimated by using the radiation-transfer simulation and nebular-continuum contributions are plotted as blue and red lines. The green curves denote the total fluxes estimated from all components.
