Notes. (a)Predicted frequency from the rotational and distortion constants derived from a fit to the lines reported by Kisiel & Kraśnicki (2010). (b)Integrated line intensity in mK × km s−1. (c)Velocity with respect to the Local Standard of Rest in km s−1. (d)Line width in km s−1. (e)Antenna temperature in milliKelvin. (f)Root mean square noise of the data. (A)Marginal detection. (B)Blended with another feature but fit to the line parameters still possible.(C)Blended with a negative feature resulting from the folding of the frequency switching data. (D)Fully blended with another feature. (E)3σ upper limit to the antenna temperature.
