Visual evidence

Figures are taken from the released technical-note package. Interpret with the original methods and limitations.

Figure 1

Left − right strobe counter for each work session, coloured by day.

Figure 2

The same 957,332 frames under the two pairing rules. Pairs that the counter rule gets right (offset 0) fall below the left panel's range.

Figure 3

The same exposures carry different counter values in the two eyes. In this session the left counter is always the right counter plus 48.

Figure 4

Exposure-start difference of every order-based pair: the rig's true stereo synchronisation.
