We present chromospheric Ca II H and K activity measurements, rotation periods, and ages for ∼1200 F, G, K, and M type main-sequence stars from ∼18,000 archival spectra taken at Keck and Lick Observatories as a part of the California and Carnegie Planet Search Project. We have calibrated our chromospheric S-values against the Mount Wilson chromospheric activity data. From these measurements we have calculated median activity levels and derived R'_HK, stellar ages, and rotation periods from general parameterizations for 1228 stars, ∼1000 of which have no previously published S-values. We also present precise time series of activity measurements for these stars.
