Influence of Gap Size and Position within Gaps on Light Levels

Table 2

Results of the polynomial models for both methods (hemispherical photographs and instantaneous measurements) and for each gap size (small, medium, and large). For each model, the estimation of coefficients and their relative probability, , and the position of maximum light are presented.
