Notes.

^(a)

Errors on periods are the standard deviation.

^(b)

Minimum count rate during time intervals when periods with >2σ are found.

^(c)

Amplitude range in counts per second (Col. 4) and in % of count rate (Col. 5) that yields >2σ detections t₂ and t₃: from (1) Schwarz et al. (2011); (2) Hounsell et al. (2010); (3) Munari et al. (2013); (4) Mason & Walter (2014); (5) Munari et al. (2007); (6) Imamura & Tanabe (2012).

^(d)

Fraction of observation time (all observations combined/in the single observation with highest fraction) detected at >95% (2σ).
