Kinematic Distances Information
Kinematic Distance (kpc): 19
Allowed Range (kpc): 17 to 20
  Only one kinematic distance solution found for this radial velocity
Inferred Shell Size
  Shell Diameter (pc): 1500
  Allowed Range (pc): 1300 to 1500
Distance Notes:
Shell clearly associated with Galactic gas, so kinematic distances relatively reliable.
