<p>(A) The MED had a significant location dependence (<i>p</i> = 1.4509×10<sup>−9</sup>). The best location for black bar fixation was 10° below the flies. (B) The fixation performance at 2 locations (−10°; 30°) was selected to show more details of the dwelling time in the whole panorama. Note the sharp peak in the dwelling time in the central quadrant (−45∼+45° area around the bar in the panorama) at the location θ = −10°; the distribution of dwelling time was quite even at the location θ = 30°. (C) Obvious location dependence in the rDT<sub>abs</sub> between the central quadrant and the rest area (<i>p</i> = 1.1145×10<sup>−8</sup>). (D) There was no obvious location dependence in the rDFS between the central quadrant and the rest area (<i>p</i> = 0.7273). These differences were quite small. The data in (A&B) are given as the mean±SEM; the data in (C&D) are shown by box plot; the red crosses represent outliers; the <i>p</i> values were calculated by the Kruskal-Wallis test; the y-axes of certain charts are truncated for compactness.</p>
