Notes. (a)Peak surface brightness for the strongest of the two hyper-fine transitions in the 27/2 and 29/2 rotational levels (see Sect. 9.1). (b)Brightness temperature derived from the peak surface brightness and restoring beam. Uncertainty derived from typical noise in channel maps ∼1−2 mJy beam−1. (c)Upper value determined from 3σ limit in channel maps.
