Kinematic Distances for Shells with |b| < 15 deg
Note: "-" signifies no constraint on item is possible,
or no second distance solution is found in inner galaxy

- a Greater distance more likely based on Galactic spiral
structure in direction of shell
- b Greater distance somewhat preferred based on Galactic spiral
structure and/or shell size.
- c Not clear if shell is associated with local or Galactic gas.
Kinematic distances could well be inaccurate.
- d Inferred shell size plausible in context of extent of
Galactic Plane
- e Seems associated with spiral structure but kinematic
distances are too large for spiral structure in this direction (actually at
2.5 kpc not 10kpm). May be affected dramatically by streaming motions.
Kinematic distances could well be inaccurate.
- f Fairly high above Galactic plane given the kinematic distance.
Kinematic distances could well be inaccurate.
- g Appears to be in the nearer of 2 spiral arms. Likely the
larger distance because a shell < 10 pc in size is unlikely if
embedded in a spiral arm.
- h Allowed distance ranges for the two solutions overlap.
Likely nearer the upper edge of range based on spiral arm locations in this
direction.
- i Appears to be part of 3rd spiral arm along line of sight
(recently discovered to extend in this direction).
