Notes.
For the fundamental peak, we show the significance that the observed Lomb-Scargle power is not due to white noise. The chance that the observed peak is due to noise was computed from the false-alarm probability (Baluev 2008).
Probability of detection of a periodic signal in the frequency interval we probed. Computed via 
, with 
(see Zavlin et al. 2000, for more details).
Computed from the maximum and minimum light-curve count-rate values (R) via 
(Fig. 3).
