Fig. 2: Gap filling versus gap closure.

a,b, Difference between gap closure (a) and gap filling (b) by presenting a sweep of the gap magnitude parameter Δ for constant Γ, and a sweep of the scattering rate parameter Γ for constant Δ, respectively. c, Example fits from our model applied to our raw data for the OD23K, OD12K and OD3K data. The zeros of the spectra are offset for better visibility, as indicated by the red marks. The black marks indicate the gap width as determined by the model.
