Gliding amplitude (A) in spectral window (I, II) shows relative prominence of spectral components, mostly intermittent CHAT, with occasional ultradian prominence. I – Amplitudogram, showing 24-h and 12-h amplitudes (solid lines) and upper limit for 24-h amplitude (dotted horizontal line). II – Gliding window of the time series (interval 28 h, increment 8 h, harmonic increment 0.1); shading of A values begins at P-value ≤ 0.05. III – Global spectral window of time series. CHAT: Circadian Hyper-Amplitude-Tension (upper 4 shadings of A from 24-h fit). **Sundays. During a 2-month section of a 5-year record of half-hourly automatically recorded blood pressures, the circadian rhythm in a human adult male is most prominent (as seen only toward the end of the first month of life in data of healthy neonates born at term or prematurely, Figs. 25,26,27,28,29,30,31,32[164].
