Kinematic Distances Information
Kinematic Distance (kpc): 1.9
Allowed Range (kpc): 1.6 to 2.3
  Kinematic Distance 2 (kpc): 9.2
  Allowed Range (kpc): 8.9 to 9.6
Inferred Shell Size
  Shell Diameter (pc): 83
  Allowed Range (pc): 70 to 100
  Shell Diameter 2 (pc): 400
  Allowed Range (pc): 390 to 420
Distance Notes:
Shell clearly associated with Galactic gas, so kinematic distances relatively reliable.
