Notes. 

(a)

Designation of galactic planetary nebulae in the catalog of Acker et al. (1992).

(b)

The position uncertainty estimated for radio interferometric observations is of the order of 1/10 of the synthesized beam, to be conservative we considered a positional error of  ~1/5 of the synthesized beam (see Sect. 2.3).

(c)

Literature reference for the quoted positions.

(d)

Simultaneous OH and continuum observations.

(e)

The relationship of JaSt 23 with IRAS 17371 − 2747 is uncertain.
