Table 1
Velocity ranges and associated locations of the clouds along the line of sight to Sgr B2.
| Location | vLSR |
|---|---|
| (km s−1) | |
| Galactic centre | <−50 |
| 3 kpc arm | −50 to −35 |
| 4 kpc arm | −30 to −10 |
| Galactic centre | −9 to 8 |
| Sgr arm | 5 to 22 |
| Scutum arm | 25 to 39 |
Notes. The combination of the velocity ranges mentioned in these papers results in some overlapping ranges. We treat clouds falling in the overlapping velocity range between 5 and 8 km s−1 as GC clouds.
