Table 2.
The mean radiance correction factor and the expanded uncertainty (2 standard deviation estimates) of the mean radiance as a function of the radius of target area being viewed. For each radius the mean radiance correction factor and the expanded uncertainty were calculated using the number of circumscribed spatial mapping points from Fig. 3
