Notes.

^(a)

These positions are shown in Fig. 1f.

^(b)

J2000 equatorial offset relative to the central position P1.

^(c)

Angular distance to P1.

^(d)

The correction of 0.1 km s^-1 discussed in Sect. 3.2.1 has not been applied.

^(e)

HC₃N 10−9 and N₂H⁺ 1−0 both have a hyperfine structure and were therefore fitted using the method “HFS” with CLASS.
