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}_,
V_p_=V_s_=V_{obs}_+0.753.
c: The hot component dominates (U-B).
d: There is also available M_V_^p^, M_V_^s^.
e: It is possible to deconvolve the photometry in V.
f: Combined M_V_.
g: The hot component dominates (B-V).
h: M_V_(hot/cool) were calculated independently during the eclipses.
i: M_V_(primary) were calculated by a deconvolution with the
M_V_(total) and M_V_(secondary):
V_p_=V_s_ - 2.5log[10^(V_total_-V_s_)/2.5) - 1].
j: M_V_ assumed from the spectral type.
k: From the Strassmeier et al. catalogue (Cat. <V/76>).
l: Distance from M_V_, V.
m: M_V_ from R, T_eff_, CB.
