Table 1: Log of observations.
Table 2: Equivalent widths and line widths (corrected for the instrumental resolution) of the strongest emission lines measured from the average of the 45 spectra obtained in December 2002.
Table 3: Radial velocities of the ${\rm H\alpha }$ emission line determined from a single-Gaussian fit to the line profile (corrected for the heliocentric velocity).
