cds-question@unistra.frdwarf-starsm-starsradial-velocityexoplanetsThe UVES (Ultraviolet and Visible Spectrometer) M Dwarf Planet Search program surveyed 40 M dwarfs and 1 M giant from 2000 through 2007 March. Two of the M dwarfs were double-lined spectroscopic binaries. The 38 single-lined M dwarfs in this survey are among the nearest and brightest M dwarfs. Starting with the reduced 1D spectra provided by the UVES team, we reanalyzed the UVES velocities of Proxima Cen as part of the "Pale Red Dot" program. The velocity rms decreased from 3.6 to 2.3 m/s. Motivated by this result, we have harvested all of the raw data from the UVES M Dwarf Planet Search from the European Southern Observatory (ESO) archives and have written custom packages to generate 1D spectra from the raw data, and velocities from the 1D spectra. The median improvement in the velocity rms from the new analysis is 1.8 m/s. Six of the 38 M dwarfs from the original study had a velocity rms<4 m/s. In the reanalysis presented here, 22 of these stars have a velocity rms<4 m/s. We improve the upper limits on possible planets orbiting these stars by a factor of typically two to three. For many of these M dwarfs, these observations represent the first epoch of high-precision velocity measurements.2019AJ....158..251Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/158/251CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/505/859 : M dwarfs radial velocities (Zechmeister+, 2009)J/A+A/541/A9 : M dwarfs activity and radial velocity (Gomes da Silva+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/158/251https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/158/251http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/158/251https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/158/251https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/158/251http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/158/251GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/158/251/table1 (UVES M Dwarf Planet Search)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/158/251/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/158/251/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/158/251/table1?GETtext/xml+votable180.050000true173.6581564-23.87087560.0055555555555555566/16391 16462 16635 16910 20515 20896 21171 21527 22626 23286 24713 25154 29374 31781 33545 34924 35288 35366 35388 35830 36174 37942 38820 40250 41252 41591 41660 42314 42982 43569 43970 44541 45434 45543 46218 47206 47337 48902 48926https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/158/251?format=asciidefaultJ/AJ/158/251/table1UVES M Dwarf Planet SearchrecnoRecord number assigned by the VizieR team.
