Fig. 3. (A) Circadian rhythms over 3 days for one animal (2224 July 2005)
shown by cosinor analysis (Nelson et al.,
1979), which fits a `best fit' cosine wave to the actual data if
such a wave form exists. Raw data are represented by the blue line and the
best-fit curve is in pink. (B) Changes in Tglobe over the
same 3 days. Note that the time of maximum Tglobe occurs
about 7 h before the time of maximum Tcarotid. In both A
and B, actual data points (diamonds) and their corresponding calculated points
(squares) are shown.
