Fig. 9
Panel a) slope as funcion of fase angle, considering a shadow-hidding opposition effect with BS0 = 1.1 and several values of hs for a spheroid with a2/a1 = 0.9 and b = 0.5 for phase angles between 0° and 60°. The curve maked with hs = 0.0 does not include the opposition effect. Panel b) The same for a2/a1 = 0.2.
