A total of 45 PNe was observed and their physical parameters (electron density and temperature) were derived. Ionic abundances were calculated using a three-level atom model and abundances were derived through ionisation correction factors. Results show low abundance objects at high galactic latitudes, indicating a possible vertical gradient inside the bulge. A few objects with low N/O ratio were found, which could have originated from old, low mass progenitors.2001A&A...380..300Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/380/300CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/84 : Strasbourg-ESO Catalogue of Galactic Planetary Nebulae (Acker+, 1992)J/A+A/373/536 : New galactic bulge PNe (van de Steene+, 2001)J/A+AS/125/289 : Planetary nebulae radial velocities (Zijlstra+ 1997)J/ApJ/515/610 : New PN in southern Galactic Bulge (Beaulieu+, 1999)J/A+A/423/199 : Chemical abundances of planetary nebulae (Costa+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/380/300https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/380/300http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/380/300https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/380/300https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/380/300http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/380/300GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/380/300/nebulae (Positions of the nebulae (from Simbad))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/380/300/nebulae?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/380/300/nebulae?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/380/300/nebulae?GETtext/xml+votable180.050000true262.467917-26.1872220.0055555555555555566/28676 28680 28696-28697 28699 28703-28704 28712 28719 28726 28738 28745 28769-28770 28774 28793 28804 28861-28862 28898 28904 28907-28909 28972 28984 29032 29039 29079 29121 29201 29207 29248 29250 42279 42284 42291 42319 42325 42335 42452 42615https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/380/300?format=asciiOpticaldefaultJ/A+A/380/300/nebulaePositions of the nebulae (from Simbad)recnoRecord number assigned by the VizieR team.
