Example of model inputs and outputs for one participant. Variables are shown for days 280–300 of a 300-day simulation for one participant from the Regular group. (A) Binned light levels in lux. (B) The two circadian pacemaker variables, x (blue) and x c (red). (C) The predicted salivary melatonin concentration. (D) The clock-time of Dim Light Salivary Melatonin Onset (DLSMO) on each day.
