Density (left-hand scale, solid lines) and velocity (right-hand scale, dashed line) profiles of the outflowing material (similar – but with different parameters – to Fig. 9 of Paper I). Blue line: spherically-symmetric and isotropic outflow corresponding to a covering factor of f_c = 1 (see text, Sect. 2.1); green lines: ejection confined in a disc of opening angle 90° (f_c = 0.71); red line: ejection confined in a disc of opening angle 74°(f_c = 0.6); The solid light-grey lines are the density profiles for f_c = 0.71 at 100 different times uniformly distributed during the non-conservative phase.
