Figure 9. LUM motion for pair of pulsed L′ and M′ gratings of 1 cycle deg⁻¹ on the green field.

Results plotted in the same format as Fig. 8. On the green field the L′ pattern must be delayed relative to M′ (○) by ≈11 ms to null the motion. Pulse duration was 15 ms; L′ and M′ contrast was 0.065 and 0.062; field luminance was 1580 Td.
