Fig. 4: Summed signals for blurred spectra.
From: Rebuilding the vibrational wavepacket in TRAS using attosecond X-ray pulses
The black lines represent the original summed signal Sk(Δt) (k = 1% or 5%), while the blue and red lines represent the summed signals \({S}_{k}^{{{{{{\rm{N}}}}}}}(\Delta t)\) in three- (N = 3) and four-state (N = 4) models, respectively. a The summed signal Sk(Δt) and the fitting one \({S}_{k}^{{{{{{\rm{N}}}}}}}(\Delta t)\) (N = {3, 4}) for the blurred spectra with instability k = 1%; b The ratio difference \({{{{{{\rm{R}}}}}}}_{{S}_{k}}^{{S}_{k}^{{{{{{\rm{N}}}}}}}}=| 1-{S}_{k}^{{{{{{\rm{N}}}}}}}/{S}_{k}| \) in the fitting for the blurred spectra with instability k = 1%. c and d are the same as a and b, respectively, but k = 5%.
