System age (tobs) and ISM density (ρISM) estimates by solving the Weaver and Lancaster models for the observed radii and velocities of the shell (25 pc and 4 km s−1, respectively) and cloudlets (31 pc and 12 km s−1, respectively).
Model | tobs (Myr) | ρIsm (amu cm−3) |
---|---|---|
Weaver Shell | 3.67 | 1.23 × 103 |
Lancaster Shell | 3.06 | 6.74 |
Weaver Cloudlets | 1.52 | 2.96 × 101 |
Lancaster Cloudlets | 1.26 | 4.87 × 10−1 |
