The observations presented here were obtained during two runs in September 1994 and November 1995 with the 1.22 m "Galileo" telescope of the Padova University. The telescope was equipped with the Cassegrain "A" prismatic spectrograph and a CCD camera. The reciprocal dispersion of the spectra obtained in such configuration was 1.56 pix-1 at . The spectral range observed in one exposure was 4350-5700 . A typical exposure time of 30 min resulted in S/N ratio of 100 at the continuum level. Fe - Ar lamp spectra (Tomov & Munari 1995) were taken between the object exposures, several times during night allowing to monitor possible instrument flexure.
Complete reduction was done with standard packages of PC-IRAF. The equivalent widths and various line profile parameters were determined with the ReWiA system (Borkowski, 1992).
Details of these data are given in Table 1.
