Note. For each identified feature, Col. 1 gives the harboring subcore; Cols. 2 and 3 the LSR velocity and the integrated flux density of the highest-intensity channel; Cols. 4 and 5 the relative positional (RA and Dec) offsets (with the associated errors) evaluated with respect to the reference feature. The derived absolute position of the reference feature is $\alpha(J2000) = 18^{\rm h} 36^{\rm m} 12\hbox{$.\!\!^{\rm s}$ }563$, $\delta(J2000) = -07\hbox{$^\circ$ }12' 10\hbox{$.\!\!^{\prime\prime}$ }792$, with an uncertainty of $\approx$50 mas in both coordinates.
