cds-question@unistra.frplanetary-nebulaegalaxiesWe present the results of an [O III] {lambda}5007 survey for planetary nebulae in the NGC 1023 Group. In all, we detected 143 planetary nebula candidates: 110 in the SB0 galaxy NGC 1023 and 33 in the halo of the edge-on Sb spiral NGC 891. Using a statistically complete and homogeneous sample of planetary nebulae and the procedures described in previous papers in the series, we derive distances to these galaxies using the planetary nebula luminosity function (PNLF). After correcting for foreground extinction by using the estimated reddening values of Burstein and Heiles, we find the distance moduli for NGC 1023 and NGC 891 are 29.97+/-0.14 and 29.97+/-.16, respectively. The similarity of these distances demonstrates the insensitivity of the PNLF to galaxy Hubble types and population age, and again confirms it as one of the best extragalactic standard candles.1991ApJ...383..487Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/383/487CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/339/53 : Paper II, M 31 (Ciardullo+, 1989)J/ApJ/344/704 : Paper III, M 81 (Jacoby+, 1989)J/ApJ/344/715 : Paper IV, Leo I group (Ciardullo+, 1989)J/ApJ/356/332 : Paper V, Virgo cluster (Jacoby+, 1990)J/ApJ/365/471 : Paper VI, Magellanic Clouds (Jacoby+, 1990)J/ApJ/416/62 : Paper IX, Fornax cluster (McMillan+, 1993)J/ApJ/462/1 : Paper X, Coma I region (Jacoby+, 1996)J/ApJ/479/231 : Paper XI, M 101, M 51, M96 (Felmeier+, 1997)J/ApJ/577/31 : Paper XII, Pop I and Pop II (Ciardullo+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/383/487https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/383/487http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/383/487https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/383/487https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/383/487http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/383/487GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/383/487/table5 (Astrometric reference stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/383/487/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/383/487/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/383/487/table5?GETtext/xml+votable180.050000true40.125247439.04791680.005555555555555556Cone search capability for table J/ApJ/383/487/table2 (NGC 1023 planetary nebulae)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/383/487/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/383/487/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/383/487/table2?GETtext/xml+votable180.050000true40.073249439.06271690.005555555555555556Cone search capability for table J/ApJ/383/487/table3 (NGC 891 planetary nebulae)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/383/487/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/383/487/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/383/487/table3?GETtext/xml+votable180.050000true35.657993742.36348550.0055555555555555566/2374 2409https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/383/487?format=asciiOpticaldefaultJ/ApJ/383/487/table5Astrometric reference starsrecnoRecord number assigned by the VizieR team.
