Data of one analysis week were used. More details on the statistical test results are listed in Supplementary Table 3. The lower the photophase-to-scotophase activity ratio, the higher the degree of nocturnality. The lower the second-to-first half of scotophase activity ratio, the higher the activity during the first half of scotophase.
