Kinematic Distances Information
    Kinematic Distance (kpc): 22
    Allowed Range (kpc): 21 to 24
    Only one kinematic distance solution found for this radial velocity
Inferred Shell Size
    Shell Diameter (pc): 380
    Allowed Range (pc): 370 to 420
Distance Notes:
       Not clear if shell is associated with local or Galactic gas. Kinematic distances could well be inaccurate.
       Fairly high above Galactic plane given the kinematic distance. Kinematic distances could well be inaccurate.
