Notes. Parameters and their values used in the best-fit model. Rmax indicates the maximum radius of the outflow. The density and temperature follow the potential laws of Eqs. (1) and (2).
and
are the values of the velocity of the disk and outflow at 1016 cm in Eqs. (4) and (5). We show the inclination of the nebula symmetry axis with respect to the line of sight and the position angle of its projection on the plane of the sky.
