cds-question@unistra.frspectroscopylate-type-starsstellar-agesI present chromospheric-activity measurements of ~670 F, G, K, and M main-sequence stars in the Southern Hemisphere, from ~8000 archival high-resolution echelle spectra taken at Las Campanas Observatory since 2004. These stars were targets from the Old Magellan Planet Search, and are now potential targets for the New Magellan Planet Search that will look for rocky and habitable planets. Activity indices (S values) are derived from CaII H and K line cores and then converted to the Mount Wilson system. From these measurements, chromospheric (log R'_HK_) indices are derived, which are then used as indicators of the level of radial-velocity jitter, age, and rotation periods these stars present.2011ApJ...734...70Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/734/70CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/239 : The Hipparcos and Tycho Catalogues (ESA 1997)III/159 : Ca II H and K Measurements Made at MWO (Duncan+ 1991)J/A+A/531/A8 : Activity indexes and vel. for 890 stars (Jenkins+, 2011)J/A+A/520/A79 : FGK stars chromospheric activity (Martinez-Arnaiz+, 2010)J/ApJ/725/875 : Chromospheric activity for CPS stars (Isaacson+, 2010)J/ApJ/687/1264 : Age estimation for solar-type dwarfs (Mamajek+, 2008)J/A+A/485/571 : Metallicities + activities of southern stars (Jenkins+, 2008)J/MNRAS/372/163 : Activity indices for southern stars (Jenkins+, 2006)J/AJ/132/161 : NStars project: The southern sample.
