Notes. The heliocentric Julian date (HJD) is given for the midpoint of each exposure. The -index values obtained for each individual spectrum are also reported. The S/N(Ca) in the range of the UV was calculated from the instrumental flux, corrected for the gain of the CCD at the centre of the 90th echelle order (~400 nm).
