Periods were obtained from periodogram analysis for flies kept in LL for at least 7 d. Values shown are means ± SEM (in hours) of two to five independent experiments, each with 8-16 rhythmic flies for each genotype and light intensity. Values for cryb ss flies are repeated from Table 1 for easier comparison. ND, Not determined.
↵ a Light intensity experienced by individual flies varied by less than a factor of two around the values shown.
