Fig21. The shapes of the single-scattering intensity phase functions used for the blue models. The peaks for scattering angles less than 9° are from the appendix of Tomasko et al. (2008) while the curves for angles greater than 9° are smoothly mated to the Henyey–Greenstein functions used in Tomasko et al. (2008) to fit the blue Solar Aureole measurements at a wide range of angles from the Sun.
