Source Data: Spatial tuning of translational optic flow responses in hawkmoths of varying body size.

The data from the population experiments (Figs. 2,3,S2) is split into two files: one for the asymmetric and one for the symmetric configuration (pop_data_sym &amp; asym). The .mat file contains the individual animal's flight tracks (first column x coordinate, second column y coordinate), as well as the respective spatial frequency "<i>conditions</i>" (indicated by an index in "<i>groups</i>", and translated to the spatial wavelength of the grating in "<i>conditions</i>"). The extracted flight data is contained in the "<i>data</i>", and the data type is given by "<i>labels</i>".<br>The data from flight tracks in which individual hawkmoths were identified (Figs. 5,6,7) is split into two files: one for the asymmetric and one for the symmetric configuration (ind_data_sym &amp; asym). The .mat file contains the size of each animal "all_anim_size" (col 1 = thorax width, 2 = animal length, 3 = inner wing length). The moths individual identity is provided by "all_IDs", and the spatial wavelength of the pattern by "all_spat_wavel", while the effective spatial frequency is given by "all_spat_freq" (calculated as the spatial frequency visible directly laterally of the average median position of the animal in the tunnel). The other variables give the 10% maximum speed (all_max_speed), the mean speed (all_avg_speed), the median lateral position in the tunnel (all_position), and the lateral position index (all_lateral_position), calculated as the amount of movement parallel and perpendicular to the main tunnel axis for each frame. <br>The data from the experiment in which a switch in pattern was presented midway down the tunnel (Figs. 4) is split into three files: the flight tracks and sigmoid fits are saved in the <br>switch_c1_tracks and c2 files, and the extracted parameters for both conditions in the switch_data file.<br>The switch_data file contains the parameters from fitting a sigmoid to the flight tracks for flights from a symmetric to an asymmetric configuration (combParamsStoA) and vice versa (AtoS), and the viewing angles based on the 10% divergence of the sigmoid fit from the baseline (viewingAngleStoA). The parameters contain the following data: col 1 = rate of change, 2 = 50% turnpoint, 3 = baseline before turning, 4 = maximum after turning, 5 = 10% deviation from baseline before turn, 6 = average flight speed before turn.<br>
