cds-question@unistra.frlate-type-starsspectroscopyThe main chromospheric activity indicator is the S index, which is the ratio of the flux in the core of the CaII H and K lines to the continuum nearby, and is well studied for stars from F to K. Another chromospheric proxy is the Halpha line, which is believed to be tightly correlated with the CaII index. In this work we characterize both chromospheric activity indicators, the one associated with the H and K CaII lines and the other with Halpha, for the whole range of late type stars, from F to M.2007A&A...469..309Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/469/309CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/331/581 : Rotation and activity in field M dwarfs (Delfosse+ 1998)J/A+AS/124/359 : CaII triplet lines in cool stars (Mallik 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/469/309https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/469/309http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/469/309https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/469/309https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/469/309http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/469/309GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/469/309/table2 (Stars included in the sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/469/309/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/469/309/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/469/309/table2?GETtext/xml+votable180.050000true5.7157844-12.20943810.0055555555555555566/4444 8843 8995 12890 16391 16678-16679 16692 16930 17137 17219 17425 17486 17606 20896 21060 21177 21386 21484 22036 22157 22708 22807 22818 23057 23177 23201 23575 24581 25316 25793 25989 26575 26583 27374 27798 27975 28696 28955 28987 29196 30505 30579 30878 30943 31073 31087 31130 31781 33243 33456 33552 33717 33818 34074 34130 34384 35079 35128 35347 35745 35875 36635 36664 36693 36697 36762 36813 37245 38219 38430 38936 38950 39257 39464 39693 39808 41591 41679 41687 41763 42248 42431 42486 42760 43187 43290 44284 44366 45472 45535 45564 45668 45927 46129 46234 46306 46523 46681 46728 46734 46777 46925 47287 47706 48283 48768https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/469/309?format=asciiOpticaldefaultJ/A+A/469/309/table2Stars included in the samplerecnoRecord number assigned by the VizieR team.
