VizieR Online Data Catalog: Coordinates of Galactic planetary nebulae (Kerber+, 2003)

The table is a compilation of the positions of 1312 Galactic PlanetaryNebulae (PNe). We have used the 2nd generation of the Guide StarCatalogue (GSC-II, Cat. ) as a reference astrometric catalogue tocompile the positions of 1086 Galactic Planetary Nebulae (PNe) listed inthe Strasbourg ESO Catalogue (SEC, Cat. ), its supplement and theversion 2000 of the Catalogue of Planetary Nebulae. This constitutesabout 75% of all known PNe. For these PNe, the ones with a known centralstar (CS) or with a small diameter, we have derived coordinates with anabsolute accuracy of ~0.35" in each coordinate, which is the intrinsicastrometric precision of the GSC-II. For another 226, mostly extended,objects without a GSC-II counterpart we give coordinates based on thesecond epoch Digital Sky Survey (DSS-II). While these coordinates mayhave systematic offsets relative to the GSC-II of up to 5 arcsecs, ournew coordinates usually represent a significant improvement over theprevious catalogue values for these large objects. This is the firsttruly homogeneous compilation of PNe positions over the whole sky andthe most accurate one available so far.(2 data files).
