{\footnotesize  Note. For each identified feature, Col.~1 gives the  label number; Cols.~2 and~3  the line-of-sight velocity  and  the integrated flux density   of the highest-intensity channel; Cols.~4 and~5  the {\it absolute} positional (RA and Dec) offsets (and, within brackets, the associated errors),  evaluated with respect to the maser position used at the correlator ($\rm \alpha(J2000) = 05^h 30^m 48\pas033$,  $\rm \delta(J2000) = 33^{\circ} 47' 54$\pas6); Cols.~6--8  the projected components along the RA and Dec axes and the absolute value of the derived proper motions (and, within brackets, the associated errors).
