These mechanisms would imprint different signatures in the galaxies' stellar kinematics out to large radii, offering a method for distinguishing between them. We aim to study a sample of six S0 galaxies from a range of environments, and use planetary nebulae (PNe) as tracers of their stellar populations out to very large radii, to determine their kinematics in order to understand their origins. Using a special-purpose instrument, the Planetary Nebula Spectrograph, we observe and extract PNe catalogues for these six systems. We show that the PNe have the same spatial distribution as the starlight, that the numbers of them are consistent with what would be expected in a comparable old stellar population in elliptical galaxies, and that their kinematics join smoothly onto those derived at smaller radii from conventional spectroscopy. The high-quality kinematic observations presented here form an excellent set for studying the detailed kinematics of S0 galaxies, in order to unravel their formation histories. We find that PNe are good tracers of stellar kinematics in these systems. We show that the recovered kinematics are largely dominated by rotational motion, although with significant random velocities in most cases.2013A&A...549A.115Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/549/A115CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/549/A115https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/549/A115http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/549/A115https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/549/A115https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/549/A115http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/549/A115GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/549/A115/pne (Catalog of PNe in 5 galaxies:)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/549/A115/pne?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/549/A115/pne?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/549/A115/pne?GETtext/xml+votable180.050000true151.2125-7.7491670.0055555555555555566/7384-7385 13401 26803 26809 27515 28200https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/549/A115?format=asciiOpticaldefaultJ/A+A/549/A115/pneCatalog of PNe in 5 galaxies:recnoRecord number assigned by the VizieR team.
