cds-question@unistra.frlate-type-starsline-intensitiesWilson & Bappu (1957ApJ...125..661W) have shown the existence of a remarkable correlation between the width of the emission in the core of the K line of CaII and the absolute visual magnitude of late-type stars. Here we present a new calibration of the Wilson-Bappu effect based on a sample of 119 nearby stars. We use, for the first time, width measurements based on high resolution and high signal to noise ratio CCD spectra and absolute visual magnitudes from the Hipparcos database.2003A&A...401..997Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/401/997CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/239 : The Hipparcos and Tycho Catalogues (ESA 1997)III/226 : Rotational Velocities of Stars (Glebocki+ 2000)III/200 : Catalogue of [Fe/H] (Cayrel de Strobel+, 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/401/997https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/401/997http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/401/997https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/401/997https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/401/997http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/401/997GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/401/997/table1 (Our data sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/401/997/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/401/997/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/401/997/table1?GETtext/xml+votable180.050000true6/8198 8333 8518 8834 12544 12720 12944 12953 16678-16679 16689 16691 16834 17028 17314 18441 18466 18498 18702 18734 18911 19045 19144 19157 19237 19286 20739 20896 21017 21089 21136 21177 21185 21568 22553 23230 24151 24921 25246 25278 25304 25407 25706 25708 25741 25910 25930 25997 26320 26538 26552 26633 27694 29024 29359 29533 29552 29923 29939 30024 30029 30064 30171 30210 30228 30234 30339 30343 30518 30541 30567 30665 30845 30921 30953 30958 31297 31408 31428 31475 31488 31585 31784 31842 31987 33210 33224 33281 33552 33717 33818 33854 33965 34442 34446 34817 34864 34990 35118 35802 35896 36232 36365 36379 37408 37595 37648 37708 38562 38913 39165 39256 39500 39709 39714 39767 40095 40408 40690 40750 40838 42383 43639 44015 44554 44799 44883 45050 45353 45472 45535 45564 45669 45843 45941 46247 46734 46776 46997 47589 47640 47678 47740 48254 48291 48576 48705 48992 49123https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/401/997?format=asciiOpticaldefaultJ/A+A/401/997/table1Our data sample[Fe/H]?
