Comments:

Kinematic Distances Information
    Kinematic Distance (kpc): 15
    Allowed Range (kpc): 14 to 15
    Only one kinematic distance solution found for this radial velocity
Inferred Shell Size
    Shell Diameter (pc): 290
    Allowed Range (pc): 270 to 290
Distance Notes:
       Shell clearly associated with Galactic gas, so kinematic distances relatively reliable.

Expansion Velocity Information
    Velocity of Front Wall V_f (km/s): -43
    Velocity of Back Wall V_b (km/s): -12
    Expansion Velocity (km/s): 16
        Back wall estimate may be possibly unrelated gas, or suffer from data quality issues.
    Minimum 'Shell-like' velocity V₁ (km/s): -31
    Maximum 'Shell-like' velocity V₂ (km/s): -18
    Lower Limit on V_exp (km/s): 13 (from V_f and V₂)
