Table 2.
Velocity limits used to produce the moment 0 maps for each C2H multiplet.
| Multiplet | Transition frequency | Velocity range |
|---|---|---|
| (GHz) | (km s−1) | |
| N = 1−0 | 87.407 | −185 to 370 |
| N = 2−1 | 174.663 | −220 to 380 |
| N = 3−2 | 262.004 | −185 to 310 |
| N = 4−3 | 349.337 | −185 to 415 |
Notes. Velocities are given according to the radio convention using the frequency of the highest Aij in each multiplet. The wide ranges account for multiple components rather than being determined by line width.
