  1. All period estimates are in hours. LS: Lomb-Scargle Periodogram, FFT: Fast Fourier Transform, MEM: Maximum Entropy Method. All LS results were significant (p < 0.001). “Non-circadian” indicates neither of the two most powerful peaks of the frequency spectra fell in the circadian range (19–29).
