Other interesting cases: preliminary results

For each source displaying a significant power spectrum peak a detailed timing and spectral analysis is carried out. So far only a 10% of the sample of candidate pulsators was analysed. In this last section some preliminary results are shown. Sampled periods range between tex2html_wrap_inline2894 and tex2html_wrap_inline2896 with a gap between 500s and 50s where the effects of the orbital motion and wobble oscillations make the detection of periodicities a very difficult task.

For each light curve the corresponding power spectrum is reported in the range of interest together with the folded light curve at the period of the corresponding detected peak (Fig. 6.26-6.33, inner panels). In Table 6.5 a summary of the major peak parameters is also reported.
