Intensity profiles of Mg II lines for events that have high intensity in the wings and small intensity in the peaks. The selection was done randomly (see the small circles in Fig. 3). The correspondence is as follows: 5 − dark blue; 6 − light blue; 7 − red; 8 − orange; 9 − light green. The black line represents the E profile. All these profiles have a shape between CB C and CB E profiles.
