Temporal behavior of the transit timing parameters of real TLCs like in Fig. 1b, compiled for a sequence of adjacent time-windows, vs. time in Julian days JD: panel a: transit start-time Δt_s. Panel b: transit end-time Δt_e. Panel c: transit duration Δt_e − Δt_s. Panel d: transit minimum-time Δt_m (maximal flux decrease). Panel e: transit shape parameter A_s. Panel f: transit flux decrease ΔF_tr.
