(Ref) Object type as listed in the reference "Ref"
(acronym) Object type linked to the acronym according to the original reference
() Anterior to 2007, before we can link the objet type to a reference, or given by the CDS team in some particular cases

Syntax of coordinates is : "ra dec (wtype) [error ellipse] quality bibcode" :
ra dec : right ascension and declination (unit and frame defined according to your Output Options)
Grey values are increasing the original precision due to the computation of frame transformations
(wtype) : wavelength class for the origin of the coordinates (Rad, mm, IR, Optical, UV, Xray, Gam)
[error ellipse] : measurement uncertainty, on (ra,dec) if the positional angle is 90 degrees, on (majaxis,minaxis) otherwise (in mas at defined epoch in the original catalogue),
position angle (in degrees North celestial pole to East)

Notes (1) :
The PN G358.3-02.5 name (from Acker et al. 1992, Cat. V/84) was assigned to this planetary nebula between Nov. 2006 and July 2010, with an erroneous position of 17 51 53.6-32 04 53 (J2000) between 2009 and 07-Sep-2010 (the declination is in error in Acker et al. cat. V/84). The correct position, agreeing with the pre-2009 position and iwth the finding charts of Allen, 1979Obs....99...83A, is 17 51 45.266 -32 03 03.84 (J2000).
