Table 4:

Frequencies (in c d^-1) deduced from the time-series analysis of various parameters (Cols. 3 to 7) of all studied lines listed in Col. 1 with the FEROS data. The symbol ``-'' means that a frequency search was performed but no significant frequency was found. The second column $V_{\rm rad}$ gives the value of the average radial velocity of each line (in km s^-1). In this column, the symbol ``-'' means that we did not calculate $V_{\rm rad}$ due to the presence of emission or blended lines.
