Figure 9
(a) U20 wavelength-normalization curve derived from MbCO data (90 frames, 2° angular increment; half of the complete data set used). The λ-curve is modeled with 128 Chebyshev terms. The measured U20 spectrum is shown for comparison (dashed line). (b) The error function plot for the λ-curve modeled with 128 Chebyshev terms. No significant systematic features near the edge are present. |
