Fit wiggle model used to correct for the resampling noise. The data points show the signal of wiggle d(λ)/T(λ) for the central spaxel on the lens galaxy, where T(λ) is obtained from the best-fit model m(λ). The orange line shows the W(λ) function in the best-fit m(λ), with the orange shaded region illustrating the 1σ confidence region. The vertical gray dashed lines show the wavelength range containing the Ca II triplets of the lens galaxy that we fit to measure the lens galaxy’s kinematics. The gray data points are rejected outliers using the false discovery rate method.
