(a) Enlarged view of the harmonic spectrum at linear polarization for H19–H23 of Fig. 1. (b) Spatially and spectrally integrated signal of H23 as a function of ellipticity. (c) Measurement of the ellipticity dependence of three different spatial–spectral parts of H23 as indicated by the three arrows. The solid lines represent Gaussian fits to the experimental data. (d) Pixel-by-pixel threshold ellipticity of the spatial–spectral region of part (a).
