Caption: Figure 7.
Upper panels: flux density of the individual v = 1 J = 1 → 0 SiO maser spot against the angular distance to the nearest v = 2 J = 1 → 0 SiO maser spot with the same velocity. Lower panels: fraction of the overlapping area of the closest v = 1 and v = 2 SiO maser spots used in the upper plot against the angular separation between those spots. Right panels: close up plots of the red dashed boxes of the left panels for a distance smaller than 1 mas. The most blueshifted (<7 km s−1) and redshifted (>13 km s−1) spots are overplotted on the rest of the spots. Color represents the velocity of the SiO maser spots shown in the all panels.
