The relationship between the ratio d and LLE in the cases of (a) P = 1.0 and (b) P = 0.5 with selected light intensity K_f. The coupling strength g is 0.04 and 0.08 in (a) and (b), respectively, and the mean of amplitude relaxation rate C is 0.01. The dotted pink lines indicate the trough d_c of the LLE and dashed green lines represent d = 1, respectively.
