Same as Fig. 16 but for the best-fitting double HG_pol scattering phase function for i = 75° and the function obtained by Milli et al. (2019) (dashed green lines): (a) calculated and measured relative quadrant values; (b) deviations of obtained values from the best-fitting solution; (c) double HG_pol phase function for the fits and the directly extracted curve from Milli et al. (2019) (dotted line and gray uncertainty range); (d) corresponding intensity phase functions.
