Figure 4
(a) The U26 wavelength-normalization curve derived from PYP data (60 frames, 1° angular increment; one half of the complete data set collected). Differences in the λ-curve as modeled with 64, 128 and 256 Chebyshev terms are shown. (b) The error function plot for the λ-curve modeled with 256 Chebyshev terms. Large scatter is present in the areas of low intensity but no significant systematic features are present near the edges. |
