cds-question@unistra.frearly-type-starsa-starsgalaxy-kinematicsWithin the scope of a Key Programme determining fundamental parameters of stars observed by HIPPARCOS, spectra of 525 B8 to F2-type stars brighter than V=8 have been collected at ESO. Fourier transforms of several line profiles in the range 4200-4500{AA} are used to derive vsini from the frequency of the first zero. Statistical analysis of the sample indicates that measurement error is a function of vsini and this relative error of the rotational velocity is found to be about 6% on average. The results obtained are compared with data from the literature. There is a systematic shift from standard values from Slk_7_5, which are 10 to 12% lower than our findings. Comparisons with other independent vsini values tend to prove that those from Slettebak et al. (1975ApJS...29..137S) are underestimated. This effect is attributed to the presence of binaries in the standard sample of Slettebak et al. (1975ApJS...29..137S), and to the model atmosphere they used.2002A&A...381..105Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/381/105CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/226 : Rotational Velocities of Stars (Glebocki+ 2000)J/A+A/335/183 : Pleiades low-mass stars rotational velocities (Queloz+ 1998)J/A+AS/126/21 : Velocities and duplicity of F-type dwarfs (Nordstroem+ 1997)J/A+AS/139/433 : RV and vsini of evolved stars (de Medeiros+ 1999)J/MNRAS/284/265 : Rotational Velocities of 373 OB stars (Howarth+ 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/381/105https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/381/105http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/381/105https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/381/105https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/381/105http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/381/105GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/381/105/table4 (Results of the vsini measurements)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/381/105/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/381/105/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/381/105/table4?GETtext/xml+votable180.050000true1.826111-17.386990.0055555555555555566/4115 16443 16491 16543 16572 16615 16629 16686 16689 16704 16844 16942 17125 17156 17194 17254 17421 17451 17573 17695 17792 17979 18049 18493 18737 18820 18957 19026 19099 19106 19567 20498 20507 20523 20612 20659 20683 20688 20725 20761 20775 20835 20841 20861 20880 20924 20938 20940 20943 20998 21047 21060 21076 21083 21089 21165 21185 21189 21229 21241 21289 21326 21362-21364 21388 21394 21399 21430 21458 21461-21462 21526 21538 21576 21582 21615 21677 21778 21788 21833 21891 21993 22058 22102 22104 22114 22215 22576 22581 22641 22753 22759 22819 22822 22849 22852 22861 22864 22874 22881 22917 22920 23076 23323 23408 23547 23552 23557 24315 24592 24645 24782 24839 24979 25015 25074 25077 25082 25110 25138 25187 25235 25259 25325 25414 25809 25854 25868 26141 26315 26671 26676-26677 26705 26728 26801 26933 27027 27029 27102 27215 27269 27282 27333 27690 28208 28737 28747 28786 28798 28852 28872 28882 29025 29073 29076 29086 29155 29161 29219 29313 29454 29661 29701 29795 29865 29922 29925 30221 30325 30467 30740 30765 30781 30874 30955 30999 31284 32788 32797 32923 33013 33037 33070 33111 33190 33193 33232 33361 33417 33430 33447 33483 33490 33496 33535 33540 33694 33800 33888 34054 34137 34217 34257 34306 34347 34458 34509 34520 34522 34536 34538 34589 34607 34680 34823 34849 34873 34941 35053 35061 35104 35163 35165 35226 35235 35304 35327 35529 35603 35617 35676 35723 35801 35836 35842 35862 35900 35967 36018 36036 36096 36104 36145 36177 36372 36560 36575 36676 36758 36773 36817 36850 36886 37063 37067 37090 37120 37154 37164 37170 37206 37235 37290 37293 37297 37312 37314 37350 37407 37463 37497 37649 37660 37686 37688 37691 37700 37724 37732 37765 37779 37816 37871 37892-37893 37900 37904 37957 37969 37978 37984 38074 38087 38100 38121 38223 38243 38296 38371 38374 38395 38429 38434 38443 38465 38489 38538 38559 38663 38719 38722 38730 38749 38806 38831 38833 38841 38893 38929 38950 38986 39085 39088 39149 39177 39263 39279 39281 39364 39373 39394-39395 39429 39486 39519 39555 39579 39608 39611 39674 39691-39692 39732 39768 39776 39841 39851 39860 39873 39885 39889 39898 39904 39918 39976 40018 40067 40072 40162 40167 40208 40306-40307 40342 40392 40400 40477-40478 40508 40528 40593 40596 40606 40660 40699 40782 40790 40807 40860 40976 40999 41103 41265 41376 41393 41439 41542 41563 41567 41622 41632 41643 41664 41726 41731 41794 41822 41842 41864 41869 41964 41985 41999 42067 42071 42186 42223 42268 42368 42375 42399 42406 42507 42587 42611 42616 42696 42740 42861 42932 43013 43051 43097 43146 43199 43206 43226 43309 43326 43333 43430 43463 43469 43507 43519 43539 43561 43647 43677 43716 43912 43914 43975 43981 44204 44226 44329 44499 44622 44998 45085 45129 45159 45247 45363 45366 45374 45443 45469 45505 45566 45624 45654 45689 45752 45784 45855 46069 46084 46096 46135 46138 46181 46430 46436 46459 46538 46740 46802 46908 46939 46979 47025 47031 47054 47086 47292 47301 47465 47481 47637 47643 47682 47727 47740 47769 47777 47842 48037 48086 48122 48124 48281 48295 48299 48727 48749 48761 48811 48876 48884 49049https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/381/105?format=asciiOpticaldefaultJ/A+A/381/105/table4Results of the vsini measurementsrecnoRecord number assigned by the VizieR team.
