Fig. 12

Normalized radiance (644 nm wavelength) measured through the optical fibre located at 10.5 ZN and 180 AA as a function of the zenith and azimuth angles. White dots represent the position of the lamp over the virtual sphere during the measurement. The intersection of the dotted red lines indicates the expected angular position of the optical fibre. The intersection of the dotted green lines indicates its actual position
