Notes. All parameters are taken from Saar & Brandenburg (1999) and Paper I. The range in P_rot has been taken from Donahue et al. (1996). Column 5 shows the cycle periods; in case there are double periodicities, they appear in the same order than in Saar & Brandenburg (1999), i.e. the primary before the secondary.
