Comparisons between flanker contrast and the null hypothesis of zero TE for the target-to-flanker distance of 8λ condition with iso-orientation at levels 0.56, 1.24, and 2.71, estimated marginal means were significantly positive (p < 0.05). Table 6 summarizes the results for different levels at 8λ.
