Table 2:

Kappa matrix photometric coefficients obtained when the light is injected only in the 4th input (F₄). The first two lines correspond to the wide band experiments while the third gives the average value over wavelength, as well as the peak-to-valley amplitude over the wavelength range (chromaticity). Values are divided by 10⁴. Bold numbers, preceded by a star, indicate the illuminated outputs.
