M5v/L5v corresponds to the mean values of the five consecutive hours of maximal (M) and lowest (L) values; M10v/L10v, mean values of the 10 consecutive hours of maximal (M) and lowest (L) values; M5h/L5h is the midpoint timing of the five consecutive hours of maximal (M) and lowest (L) values; M10h/L10h, midpoint timing of the 10 consecutive hours of maximal (M) and lowest (L) values. DSPD, delayed sleep phase disorder. A.U. = arbitrary units.
