cds-question@unistra.frstellar-atmospheresdwarf-starsWe have acquired high-resolution echelle spectra of 225 F6-M5 type stars in the Southern hemisphere. The stars are targets or candidates to be targets for the Anglo-Australian Planet Search. CaII H&K line cores were used to derive activity indices for all of these objects. The indices were converted to the Mt. Wilson system of measurements and logR'_HK_ values determined. A number of these stars had no previously derived activity indices. In addition, we have also included the stars from Tinney et al. (2002MNRAS.332..759T) using our Mt. Wilson calibration. The radial-velocity instability (also known as jitter) level was determined for all 21 planet-host stars in our data set. We find the jitter to be at a level considerably below the radial-velocity signatures in all but one of these systems. 19 stars from our sample were found to be active (logR'_HK_>-4.5) and thus have high levels of jitter. Radial-velocity analysis for planetary companions to these stars should proceed with caution.2006MNRAS.372..163Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/372/163CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/76 : Chromospherically Active Binaries (Strassmeier+ 1993)J/A+A/312/221 : Excess CaII H+K emission in active binaries (Montes+, 1996)J/AJ/111/439 : Chromospheric emission in late-type stars.
