Spatial distribution of the wind velocities. (Left panel) Plot of the maser V_LSR versus positions projected perpendicular to the jet axis, R_per (taken positive toward PA = 160°). The colors of the error bars indicate the position projected along the jet axis, R_axi (taken positive toward PA = 70^°), as denoted by the wedge to the right of the panel. The two dashed vertical and horizontal lines mark the position and V_LSR of the YSO, respectively. The dotted rectangle delimits the water masers with blueshifted V_LSR at positive R_per. (Right panel) Plot of the maser velocity component parallel to the jet, V_axi, versus the absolute value of R_per. Colors have the same meaning as in the left panel.
