Here we provide the raw data for all three experiments from our paper. Subjects adapted to flickering gratings and their task was to detect a target grating at one of four locations. We manipulated target onset (gradual or abrupt), target orientation (parallel or orthogonal to adapting grating in Experiment 2, and at a range of orientations in Experiment 3). The experiments are provided in full in the paper, which is under review at i-Perception; the preprint is at BiorXiv at http://biorxiv.org/content/early/2016/04/15/048918
