Galactic Planetary Nebulae and their central stars. I. An accurate and homogeneous set of coordinates. Kerber F., Mignani R.P., Guglielmetti F., Wicenec A. <Astron. Astrophys. 408, 1029 (2003)> =2003A&A...408.1029K
ADC_Keywords: Planetary nebulae Keywords: planetary nebulae: general - catalogs - astrometry - astronomical data bases: miscellaneous Description: The table is a compilation of the positions of 1312 Galactic Planetary Nebulae (PNe). We have used the 2nd generation of the Guide Star Catalogue (GSC-II, Cat. I/271) as a reference astrometric catalogue to compile the positions of 1086 Galactic Planetary Nebulae (PNe) listed in the Strasbourg ESO Catalogue (SEC, Cat. V/84), its supplement and the version 2000 of the Catalogue of Planetary Nebulae. This constitutes about 75% of all known PNe. For these PNe, the ones with a known central star (CS) or with a small diameter, we have derived coordinates with an absolute accuracy of ∼0.35" in each coordinate, which is the intrinsic astrometric precision of the GSC-II. For another 226, mostly extended, objects without a GSC-II counterpart we give coordinates based on the second epoch Digital Sky Survey (DSS-II). While these coordinates may have systematic offsets relative to the GSC-II of up to 5 arcsecs, our new coordinates usually represent a significant improvement over the previous catalogue values for these large objects. This is the first truly homogeneous compilation of PNe positions over the whole sky and the most accurate one available so far. File Summary:

Note (1): Note on ID number from GSC-II: This is the ID as contained in the full GSC-II catalogue version 2.1.1. If this field is empty no associated GSC-II object has been identified. Some of the IDs can not be found in the public version of the GSC-II 2.1.1 since it has limiting magnitudes of F=18.5, J=19.5, V=19.5. Note (2): GSC-II Epoch: Epoch from the GSC-II catalogue. If this field is 0.000 no associated GSC-II object has been identified. Note (3): Distance: The distance in arcsec from the original position as found in the input catalogues. Note (4): Position angle: The position angle north over east to the original position as found in the input catalogues. Note (5): Classification uses the following symbols: CS = A central star is known or recognizable, clearly separated from the nebula. ST = The nebular itself is stellar like or unresolved PHOT = The nebula is either resolved or extended with a well defined photometric center. GEO = The nebula is extended either ring-like or symmetric in general, or with a more complex morphology and no well defined photometric center.
History: * 28-Nov-2003: Prepared by F. Kerber [ESO] * 06-May-2004: for 10 stars, the minus sign of the declination was missing. * 03-Mar-2005: Names corrected (O instead of 0)
