Relation between the bulge triaxiality and the λ_e kinematic parameter computed for the galaxy as a single component, in major and minor merger simulations. Stars: for the remnants of our minor merger models with original S0b and S0c galaxies (empty blue and green ones, respectively) and our original S0 galaxies (filled blue and green ones). Crosses: for the elliptical remnants of Jesseit et al. (2009) that are fast rotators in all projections (light green), that are fast rotators but that are identified as slow rotators in some projections (orange), and those that are slow rotators (red). Median error bars in both axes are plotted in the upper left corner of the frame. (This figure is available in color in electronic form.)
