Labelled markers per trial in a local coordinate system. The labelled markers for each of the pursuit (a) and the obstacle avoidance trials (b) are shown in a coordinate system that moves with the headpack. In (a) the visual coordinate system is used and in (b) the headpack coordinate system is shown; both correspond to the template used for procrustes labelling in each trial. We considered all rendered frames in which the headpack transform was not interpolated. Note that we used different headpack designs for the two trials. The obstacle avoidance trial consists of the two obstacle avoidance flights analysed in the main text
