ABSTRACT. A re-analysis of a comprehensive survey of radio fluxes for chromospherically active binary systems is given. The correlation between activity and a convection-dependent Rossby number is found to be marginally better than correlations with simple rotation parameters. It is suggested that the evolved state of RS CVn binaries and the tidal effects on convection dynamics requires an improved convection-dependent parameter for use in rotation-activity studies.
