Relationship between the duration of the quiet phase (QP) and the puffing phase (PP) in each cycle. One day long data on July 28, 2014 shown in Fig. 2 were investigated and 150 cycles were identified. Duration of the QP is distributed in the narrow range of 149.85 ± 26.79 s and that of the PP widely varies in the range of 303.95 ± 233.05 s.
