Notes. Masses [M1, M2] of primary and secondary bodies are given in Sun mass unit M⊙. The typical stellar radius R and the typical distance D between the two bodies is given in Sun radius unit R⊙. The spin and orbital periods [Ts, Torb] are expressed in days. They yield the spin and angular velocities [Ωs = 2π/Ts, Ωorb = 2π/Torb]. The typical surface magnetic field 
, believed to be of fossil origin, is given in kiloGauss (kG) for the two components. HD 156324 and HD 98088 are synchronised systems (see Appendix D), whereas ϵ Lupi system is not synchronised.
