2 Observations and data reduction

The spectroscopic echelle observations of the chromospherically active binaries analysed in this paper were obtained during four observing runs. Two of them were carried out in 1-2 March 1996 (NOT96 hereafter) and in 5-10 April 1998 (NOT98 hereafter), using the 2.56 m Nordic Optical Telescope (NOT) located at the Observatorio del Roque de Los Muchachos (La Palma, Spain). The Soviet Finnish High Resolution Echelle Spectrograph (SOFIN) was used with an echelle grating (79 grooves/mm), camera Astromed-3200 and a 1152 $\times$ 770 pixel EEV P88200 CCD detector. The wavelength range covers from 3765 to 9865 Å, for the first run, and from 3632 to 10 800 Å, for the second run. The reciprocal dispersion ranges from 0.07 to 0.18 Å/pixel and the spectral resolution, determined as the full width at half maximum (FWHM) of the arc comparison lines, ranges from 0.15 to 0.60 Å, in both runs.

We also analyse echelle spectra obtained during a 10-night run in 12-21 January 1998 (McD98 hereafter), using the 2.1 m Otto Struve telescope at McDonald Observatory (Texas, U.S.A.) and the Sandiford Cassegrain Echelle Spectrograph (McCarthy et al. 1993). This instrument is a prism cross-dispersed echelle mounted at the Cassegrain focus and it is used with a $1200\times 400$ Reticon CCD detector. The spectrograph setup was chosen to cover the H$\alpha$ (6563 Å) and Ca  II IRT (8498, 8542, 8662 Å) lines. The wavelength coverage is about 6400-8800 Å and the reciprocal dispersion ranges from 0.06 to 0.08  Å/pixel. The spectral resolution, determined as the FWHM of the arc comparison lines, ranges from 0.13 to 0.20 Å. In one of the nights, we changed the spectrograph setup to include the He I D₃ (5876 Å) and Na  I D₁ and D₂ (5896, 5890 Å) lines, with wavelength coverage of 5600-7000 Å.

In addition, we dispose of echelle spectra taken in 7-8 January 1999 (INT99 hereafter), with the 2.5 m Isaac Newton Telescope (INT) at the Observatorio del Roque de Los Muchachos (La Palma, Spain) using the ESA-MUSICOS spectrograph. This is a fibre-fed cross-dispersed echelle spectrograph, built at the ESA Space Science Department in ESTEC as a replica of the first MUSICOS spectrograph built at Meudon-Paris Observatory (Baudrand & Böhm 1992) and developed as part of MUlti-SIte COntinuous Spectroscopy (MUSICOS) project. During this observing run, a $2148\times2148$ pixel SITe1 CCD detector was used obtaining wavelength coverage from 3950 Å to 9890 Å. The reciprocal dispersion ranges from 0.06 to 0.12 Å and the spectral resolution (FWHM of the of the arc comparison lines) from 0.15 to 0.4 Å.

In Table 1 we give the observing log. For each observation we list date, UT, orbital phase ($\varphi$) and the signal to noise ratio (S/N) obtained in the H$\alpha$ line region. Table 2 shows the HD number, name and stellar parameters of the active binary systems and the non active stars used as reference stars in the spectral subtraction. The B-V and V-R color indexes and the radius are obtained from the relation with spectral type given by Landolt-Börnstein (Schmidt-Kaler 1982) when individual values are not given in the literature. Other parameters are given by CABS Catalog (Strassmeier et al. 1993) or taken from the references given in the individual results of each star.

The spectra have been extracted using the standard reduction procedures in the IRAF package (bias subtraction, flat-field division and optimal extraction of the spectra). The wavelength calibration was obtained by taking spectra of a Th-Ar lamp, for NOT and McDonald runs, and a Cu-Ar lamp, for INT run. Finally, the spectra have been normalized by a polynomial fit to the observed continuum.
