Notes: spectral types are from the Catalog of Active Binary Stars (CABS) by Strassmeier et al. (1993) except for HU Vir (see Fekel et al. 1999; Montes et al. 2000). The B-V colour the parallax $\pi$ , the absolute visual magnitude $M_{\rm V}$ , and the amplitude of its variations ${\Delta} M_{\rm V}$ are from the HIPPARCOS Catalogue and its Variability Annex.
The photometric periods P are indicated in Col. 4 together with the corresponding reference: ¹ Variability Annex to the Hipparcos Catalogue; ² CABS; ³ Hipparcos Input Catalogue.
For objects with double-lined spectra, the last column indicates which one of the stellar components is the active star, according to the following sources: ^a Gunn et al. (1998); ^b Fernández-Figueroa et al. (1986); ^c Fernández-Figueroa et al. (1994); ^d Montes et al. (1995a); ^eMontes et al. (1995b); ^f Montes et al. (1996); ^g Montes et al. (1997); ^h Pagano et al. (2001); ⁱ Fekel et al. (1999).
