Example skin temperature data with search limits for tracking (a) start of menstruation and, (b) ovulation. The narrow solid line represents the daily temperature values. The thick solid line represents the fitted menstrual cycle component and marks x and + maximums and minimums of the fitted component, respectively. Search limits are presented as dashed rectangles A1-A3 and B1-B3. The algorithm for tracking the start of menstruation used A1-A3. The algorithms for ovulation tracking used the following search limits: HALF_LOCS, B1-B3; HALF_PEAKS, B1; and RISE_0.15, B1 and B3
