Cosinor Progressive Analysis at a spectrum of periods:  252 hr -- 9.5 hr, incremented by .5 hr

Below is the (partial) output of calculations, and below that a heat map, resulting from the progressive analysis of blood pressure for the first 40 days of life of a healthy male newborn.  Parameters used for the run are listed at the top.  304 pages of listing is generated, in total, but only a few are shown here. 
Figure 22:  CAT Cosinor Progressive analysis of heart rate rhythm over the first 40 days of a newborn.  At birth, several periods longer than 24-hr are present, gradually changing, to a 24-hr and 12-hr periods.  Progression:  168 span, moved by 12 hour increments, for the full 40 days.
