The phase was calculated using the time reference HJD = 245 4200.0. Idem as Table 1 for the errors. The signal-to-noise ratio obtained with the program pasper is given in Col. 8. The last column indicates the interpretation for each frequency as independent, harmonic, or combination, following the present frequency resolution, which is 1/T=0.037 $\mbox{c~d}^{-1}$ . Long-term frequencies are marked with ${F}_{{\rm L}}$ . For details, see text.
