Time-domain evolution of RSB in the BRFL under P/Pth = 1.2. a The spectra of the beat signal within 1000 ms above the laser threshold. b |qmax| in 20 subsequent time windows with a time interval of 50 ms. c P(q) within sub-time windows of τ2,τ10 and τ12. d P(q) within sub-time windows of τ8,τ11 and τ18
