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 cylinder defining the finger, and h its height. “offset” refers to the displacement of the centre of a given structure from the central star, in the direction defined by PA and i. PA and i are the position angle and inclination of the symmetry axis of the structure, as defined within the SHAPE modifier “PA/Inc Rotation”. δV, n, and T are the microturbulence velocity, the density, and the temperature, respectively. Vexp is the expansion velocity of the given structure. The velocity of the inner section of each finger is a constant value. The value of the velocity shown for the outer section is the velocity of the farthest edge from the star, with the velocity following a ballistic expansion pattern.
