Notes.

(a)

The fitted frequency was derived by a fit to our data using the CN N = 2−1, J = 5/2−3/2, F = 7/2−5/2 transition as reference, the catalogue frequency is taken from the CDMS catalogue of Müller et al. (2001). The uncertainty in the last digits is indicated between brackets. The shift between the two is similar to that reported for a subset of transitions in Teague et al. (2016).

(b)

At the brightest CN emission peak (see text).

(c)

The 1σ limit of the circular polarisation fraction.

(d)

The 1σ magnetic field limit. Because no detection is made, we cannot determine the sign of the magnetic field.
