Probability Distribution Function of the period Prot as recovered from 10 000 realizations by time-shuffling, considering all the cases (solid black line) or the realizations returning a 
lower than 4 times the best-fit χ2 for Model A (dot-dashed red line; see Sect. 2.2.4). The dashed vertical lines bracket the 3σ interval around the best-fit period of 10.8 days.
