cds-question@unistra.frgalaxiesplanetary-nebulaeh-ii-regionsspectroscopyImages obtained with the CTIO 4-m telescope and the MOSAIC-2 wide field camera in [OIII] 5007 and Halpha on-band and off-band filters are analyzed to search for emission line objects in the dwarf galaxy NGC 6822. In particular we search for planetary nebula (PN) candidates. In addition, imaging and spectroscopy of a sub-sample of objects obtained with the ESO VLT and FORS 2 spectrograph are used to calibrate the MOSAIC imaging. In the continuum-subtracted images, a large number of line emission regions were detected, for which we measured instrumental magnitudes in all the filters. The [OIII] 5007 and Halpha+[NII] magnitudes were calibrated with the spectroscopy.2009A&A...495..447Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/495/447CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/109/173 : BVR photometry of NGC 6822 (Marconi+ 1995)J/AJ/121/2020 : CTIO and WFPC2 photometry in NGC 6822 (Bianchi+, 2001)J/AJ/123/832 : C star population in NGC 6822 (Letarte+, 2002)J/AJ/128/2815 : ARAUCARIA: NGC 6822 Cepheid variables (Pietrzynski+, 2004)J/A+A/450/873 : ARAUCARIA: NGC 6822 bright variables (Mennickent+, 2006)J/ApJ/647/1056 : ARAUCARIA: NGC 6822 Cepheid variables (Gieren+, 2006)J/A+A/429/837 : IJKs photometry of late-type stars in NGC 6822 (Cioni+, 2005)J/A+A/431/1189 : BV photometry of NGC 6822 variables (Baldacci+, 2005)J/A+A/454/717 : Near-IR photometry of C & AGB stars in NGC 6822 (Kang+, 2006)J/A+A/456/905 : JKs, i'g'r' photometry of C stars in NGC 6822 (Demers+, 2006)J/AJ/132/378 : HST and UV photometry of NGC 6822 (Bianchi+, 2006)J/AJ/132/1372 : Chandra observation of NGC 6822 (Tennant+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/495/447https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/495/447http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/495/447https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/495/447https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/495/447http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/495/447GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/495/447/table2 (Characteristics of emission line objects in NGC 6822)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/495/447/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/495/447/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/495/447/table2?GETtext/xml+votable180.050000true296.1477083-14.68069440.0055555555555555566/29716 29718https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/495/447?format=asciiOpticaldefaultJ/A+A/495/447/table2Characteristics of emission line objects in NGC 6822recnoRecord number assigned by the VizieR team.
