Data obtained by self measurement every 2–4 h during waking only for 10 days. Any series with a significant trend had the trend removed before analysis for circadian rhythm by the least squares fit of a 24.0 h cosine. Each series was also analysed for best fitting cosine in the circadian domain between 14 and 34 h. | ||||||||||||||||||||||
For rhythm characteristics: p value from zero amplitude test; M=mesor (middle value of fitted cosine); A=amplitude (distance from M to peak or trough of cosine); %A=% amplitude (A as % of M); bØ=bathyphase (lowest point of fitted cosine, referenced from 00:00h). | ||||||||||||||||||||||
