Description:
We included 2 tables containing photometric data, together equivalent
width of LiI6708 A, for a sample of dwarf components of
Chromospherically Active Binaries (CABs).

Note (1): Spectral type between brackets are assumed from the photometry
Note (2): a: The color indices include the contribution of the secondary,
except when the color for the secondary is given.
b: Two equal stars: (U-B)p=(U-B)s=(U-B){obs},
Vp=Vs=V{obs}+0.753.
c: The hot component dominates (U-B).
d: There is also available MVp, MVs.
e: It is possible to deconvolve the photometry in V.
f: Combined MV.
g: The hot component dominates (B-V).
h: MV(hot/cool) were calculated independently during the eclipses.
i: MV(primary) were calculated by a deconvolution with the
MV(total) and MV(secondary):
Vp=Vs - 2.5log[10^(Vtotal-Vs)/2.5) - 1].
j: MV assumed from the spectral type.
k: From the Strassmeier et al. catalogue (Cat. V/76).
l: Distance from MV, V.
m: MV from R, Teff, CB.
