Notes. The respective columns list the observed transition, the rest frequency νcat (obtained from CDMS), the upper-level energy Eup, the velocity range covered by the emission features relative to the stellar LSR velocity, νLSR, i.e. 33.7 km s-1, the velocity resolution δν, the velocity-integrated intensity, i.e. total line flux, of the emission, the rms noise level at the given δν, the FWHM beamwidth or the aperture size corresponding to the (extracted) observations, and the size of the emission region estimated based on the velocity profile given by Decin et al. (2010).
