Notes. CO and H2O emission is discussed in Lefloch et al. (2010). Peak velocity and intensity (in $T_{\rm a}$ scale), integrated intensity ( $F_{\rm int}$), as well as the terminal velocities of the line emission ( $V_{\rm min}$ and $V_{\rm max}$) are reported. (a) Frequencies and spectroscopic parameters have been extracted from the Jet Propulsion Laboratory molecular database (Pickett et al. 1998) for all the transition except those of CH3OH, which have been extracted from the Cologne Database for Molecular Spectroscopy (Müller et al. 2005). Upper level energies refer to the ground state of each symmetry. (b) Gaussian fit.
