Mach bands as empirically derived associations -- Lotto et al. 96 (9): 5245 Data Supplement - View Better Figures -- Proceedings of the National Academy of Sciences

Supplementary material for Lotto et al. (1999) Proc. Natl. Acad. Sci. USA 96(10), 5239-5244 and Lotto et al. (1999) Proc. Natl. Acad. Sci. USA 96(10), 5245-5250.

The reproduction of the accompanying figures was unsatisfactory due to the presence of moiré patterns and other deficiencies in the published version. As a result, the visual effect of Mach bands, the subject of these papers, is not always well seen. Given the difficulty of faithfully reproducing gradients in print, readers may wish to view the electronic versions of the figures at purveslab.neuro.duke.edu.
