Figure 1

All participants. Data on the rest-activity cycle in 10 healthy persons for 10 days around the transition into DST in 2003. Graphics consist of four panels. The first panel from the top shows the original raw data, the second the circadian effect, the third the trend effect and the fourth the remainder. The remainder cannot be explained by the circadian nor trend effects. The scale bars to the right represent the corresponding unit in each figure.
