Notes. We display in the table the rotational temperature Trot, source-averaged column density Ns, beam-averaged column density Nb, velocity width Δv, velocity offset from systemic velocity, and abundances. If two entries per transition are given, they refer to the cold extended envelope and the hot compact core.
