Maps of the infall signatures. The maps were produced by integrating the flux density within 55–64 km s^-1 for H₂O 17_4,13 → 16_7,10 and within 57–67 km s^-1 for TiO J = 11 → 10Δ₃ (cf. Fig. 5). The water line at this range is dominated by absorption (negative flux), which is shown with green dashed contours, and residual emission outside the stellar disk (positive flux), which is shown with solid contours. The infall in the TiO line is seen mainly in emission (solid contours). The symbols have the same meaning as in Fig. 6.
