cds-question@unistra.frradial-velocitysolar-system-planetsFrom 1980 to 1992, the radial velocities of 17 bright solar-type dwarf and 4 subgiant stars were monitored at the Canada-France-Hawaii 3.6-m telescope (CFHT). Introduction: The experimental technique, in which lines of the 870 nm 3-0 vibration-rotation band of hydrogen fluoride are imposed in absorption on the stellar spectra to act as wavelength fiducials, is capable of measuring long-term changes in the velocity of a star with a precision near 15 m/s from a single spectrum. For comparison, the orbit of the Sun about the barycentre, which is dominated by the motion of Jupiter, has a period of 11.9 years with an amplitude of some 13 m/s. Thus, by making several observations per year, we could have detected the reflex motion caused by a Jupiter-mass planet orbiting a nearby star provided the orbital plane was close to the line of sight. To date, this planetary search has been the only long-term program on the CFHT. Between three and six pairs of nights per year were allocated over twelve years, apart from a single gap of six months in 1983. The 15 m/s precision per observation was achieved to a limiting I magnitude of 4 for exposures of typically less than half an hour. The program was completed in 1992. In the published paper the analysis of the 1082 individual differential velocities that are catalogued here is presented.1995Icar..116..359Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/III/185CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=III/185https://vizier.iucaa.in/viz-bin/VizieR-2?-source=III/185http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=III/185https://vizier.cds.unistra.fr/viz-bin/votable?-source=III/185https://vizier.iucaa.in/viz-bin/votable?-source=III/185http://vizieridia.saao.ac.za/viz-bin/votable?-source=III/185GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table III/185/stars (List of stars observed)https://vizier.cds.unistra.fr/viz-bin/conesearch/III/185/stars?https://vizier.iucaa.in/viz-bin/conesearch/III/185/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/III/185/stars?GETtext/xml+votable180.050000true26.017083-15.93750.0055555555555555566/3102 6066 7238 8790 10375 13301 14278 15597 16069 17425 22300 22708 23230 24151 24924 26975 29196 30529 36697https://cdsarc.cds.unistra.fr/viz-bin/moc/III/185?format=asciiOpticaldefaultIII/185/table1Catalog of precise radial velocities of 21 near-by starsrecnoRecord number assigned by the VizieR team.
