Notes. For each line datacube, we report the spectral resolution (dV), r.m.s. per channel, FoV, and synthesised beam. (a) The spectroscopic parameters (line frequency, ν0, upper level energy, Eup, line strength, S μ2, and Einstein coefficients, log (Aij)) are taken from Lowry Manson et al. (1977) (SiO), Xu & Lovas (1997) (CH3OH), Gottlieb et al. (2003) (CS), Klaus et al. (1996), and Bogey et al. (1997) (SO), retrieved from the Cologne Database for Molecular Spectroscopy (CDMS) database (Müller et al. 2005). (b) Two SiO(2–1) datacubes were produced: one cube at the spatial resolution resulting from the uv coverage of our observations, and a second cube restored with a larger synthesised beam for a proper comparison with the CH3OH and SO data. (c) No detection along the outflows. (d) The line is blended at the current spectral resolution (see Fig. 7).
