(a)Comparison of the scattering coefficient for the boundary pixel vs. illuminated fiber as determined with a D_alpha lamp in the laboratory  and through the SVD analysis of plasma discharges. (b) Comparison of the average cold D_alpha light that was employed in the SVD analysis with the measured intensity of the D¦Á lamp (multiplied by 1000) vs. fiber. 

Figure 18
Time evolution of the measured net baseline and corrected ones using SVD, and D_alpha lamp for the fiber at R = 117 cm. Here, the net baseline value is estimated by the difference of the measured baseline at the active and reference views. The baseline is defined as the mean counts in the wavelength range 661.5-661.8 nm in the red-shift side.
