Notes. The sizes correspond to a distance to the nebula of 1.17 kpc. The uncertainty range is included for every parameter except for those concerning the geometry. Parameters: r is the radius of the blob. x, y, z are the offsets of the blob with respect to the central star, defined with x increasing towards west, y increasing towards north, and z increasing along the observer-object line. δV, n, and T are the microturbulence velocity, the density, and the temperature, respectively. Vexp is a single, constant value representing the expansion velocity.
