Real eye calibrated gaze signals of dataset one. Top: representative segment of calibrated P-CR signals from S03 as processed by three different CR center localization methods. The signals contain two small saccades and have been vertically offset for clarity. RMS precision for the shown segments are 0.040^∘ for the threshold signal, 0.034^∘ for CNN, and 0.046^∘ for radial symmetry. Further, an accuracy comparison (bottom left panel), an RMS precision comparison (bottom middle panel) and an STD precision comparison (bottom right panel) between the three methods on data of three participants are shown. Error bars depict standard error of the mean
