I present an empirical model for predicting a star's radial velocity jitterfrom its B-V color, activity level, and absolute magnitude. This model is basedon observations of 450 well- observed stars from Keck Observatory for theCalifornia and Carnegie Planet Search Program. The model includes noise fromboth astrophysical sources and systematic errors, and describes jitter asgenerally increasing with a star's activity and height above the main sequence.Comment: 16 pages, 7 figures, PASP in pres
