Notes. For each source, we give the position of the peak emission of the 28SiO (v = 1, J=1–0) transition, which we used as a reference for self-calibration. The positions of all other velocity components and transitions are compatible with this one, within the errors. Speak and Vpeak are the flux density and velocity, respectively, of the maximum emission of each transition. Flux density upper limits are at a 3σ level. ∫ SνdV is the velocity-integrated flux density over the whole spectrum. The range of velocities over which emission is detected is given by Vmin and Vmax. Uncertainties of the flux density and the velocity-integrated flux density are at 1σ level. Velocities are given with respect to LSR.
