Notes. Identification of the coma structures as shown in Fig. 5. The given position angles refer to the center lines of the structures and may have a maximuma uncertainty of ± 10°. North = 0°, East = +90°. PsAng is the position of the extended Sun-comet vector. The dash indicates that the structure was not detected.
